                               =========

1. Versions of SETUP.EXE prior to Version 1.12 refused to Install or
   Update (just Remove) with certain disk utilities (like Stacker 2.0)
   and missing or Non-DPMI 1.00 compliant memory managers.  SETUP.EXE
   is very careful about modifying files and always makes a backup of
   any file prior to modification. If it could not do this, it did not
   allow you to proceed and gave you only the option to Remove. This
   problem has been fixed and appologies are due to all who received
   erroneous messages and were unable to Install the demo software.

2. SETUP.EXE may not detect other types of digitizer drivers and
   software runnning under Windows or DOS. This will often show up as
   the error "Comm Port Missing" reported on the 'Status=' line in the
   [Virtual Tablet] section of SYSTEM.INI. If you are installing the
   Virtual Tablet Interface over other digitizer software, make sure
   that software is disabled either before or right after installation.
   Refer to the software manual for those products and check your
   AUTOEXEC.BAT, CONFIG.SYS, WIN.INI and SYSTEM.INI files.

                              VERSION 1.20
                            ===============
                            (April 24, 1992)

GENERAL
~~~~~~~

1. IMPROVED: All aspects of the Virtual Tablet Interface have been
   updated to conform with the Microsoft Windows Style Guide dated
   March, 1992. This mostly applies to dialog boxes and help menus.

DOCUMENTATION (VtDocs.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~~~

1. IMPROVED: The manual is now provided in Windows Write format. Print
   and assemble in the following order: Cover, Contents, Part1, Part2,
   Part3 and Part4.

SAMPLES (VtSams.Zip)
~~~~~~~~~~~~~~~~~~~~

1.  NEW: In addtition to the Virtual Tablet Editor, sample templates
    now include skeleton templates which you may edit, embellish or use
    'as is' for the following applications: AutoCAD for Windows, Adobe
    Illustrator, CorelDRAW!, Micrografx Designer, FrameMaker, Aldus
    FreeeHand, ImageIn, Aldus Persuasion, Aldus PageMaker, PhotoStyler,
    Stanford Graphics, Ventura Publisher for Windows, Fractal Painter
    and WinCAD. See the Editor's template for an example of what a
    little extra effort can do to embellish a template.

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: A new style dialog box now includes hard-coded multiline
    labels, triangle and diamond shapes.

2.  NEW: Context-sensitive help is now available from within any menu
    and dialog box by pressing the F1 key.

3.  NEW: The help menu now includes an option to search for help by
    keyword. Choose "Search for Help on...". The Editor template has
    been updated, as well.

4.  IMPROVED: All file dialogs have been updated to conform to the new
    Common Dialog standard in Windows 3.1. This includes the "Open",
    "SaveAs", "Import" and "Export" file dialogs.

VTLOAD.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: Context-sensitive help is now available from within any menu
    and dialog box by pressing the F1 key.

2.  NEW: The help menu now includes an option to search for help by
    keyword. Choose "Search for Help on...".

3.  IMPROVED: File dialogs have been updated to conform to the new
    Common Dialog standard in Windows 3.1. This includes the "Open" and
    "SaveAs" file dialogs.

4.  FIXED: Control characters in templates did not work correctly when
    sent to Multiple Document Interface applications. This problem has
    been fixed in the current version.

VTABLET.DLL (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: Specific support has been added for SummaSketch II and
    DrawingBoard II series of digitizers. See DIGITIZE.TXT for their
    configurations. Previous versions are still compatible with both
    series but for optimum performance, use the new tablet identifiers.

2.  IMPROVED: The interrupt configuration parameter is no longer
    needed. The driver now supports only Comm 1 or 2 and uses industry
    standard comm port parameters (base, interrupt, vector, etc).

3.  FIXED: Emulation of smaller tablets such as the SummaSketch 1201 by
    larger tablets could cause a crash in absolute mode due to the
    active area size differences. The driver now bounds all incoming
    coordinates to their expected values.

VTABLET.SYS (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: Specific support has been added for SummaSketch II and
    DrawingBoard II series of digitizers. See DIGITIZE.TXT for their
    configurations. Previous versions are still compatible with both
    series but for optimum performance, use the new tablet identifiers.

2.  IMPROVED: The interrupt configuration parameter is no longer
    needed. The driver now supports only Comm 1 or 2 and uses industry
    standard comm port parameters (base, interrupt, vector, etc).

VTCONFIG.DLL (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  FIXED: A problem dating back to Version 1.00 which did not swap the
    mouse buttons correctly has been fixed.

########################################################################

                              VERSION 1.12
                            ===============
                            (April 12, 1992)

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1. NEW: Tiny and Huge font sizes have been added to style labels. Font
   sizes now map to 1/100th (Tiny), 1/80th (Small), 1/60th (Medium),
   1/40th (Large) and 1/20th (Huge) of the active area. Existing
   templates may need to be tuned to these new font sizes.

2. NEW: Button outline pen styles have been added. Give your template
   that 'Windows' look! Try elliptic buttons for important commands.

3. IMPROVED: Combinations now automatically provide an inside margin
   eliminating style conflicts with their member regions.

4. IMPROVED: The Build command has been enhanced and can now build
   templates for even the most sticky, non-standard Windows Apps (like
   Ventura Publisher). No more rolling menus prior to building.

########################################################################

                              VERSION 1.11
                            ===============
                            (April 6, 1992)

VTABLET.386 (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1. NEW: This new enhanced mode windows driver significantly speeds up
   Windows running in enhanced mode. Tablet interrupts are now handled
   down in the Virtual Machine and not in the Windows kernel. Depending
   on your tablet model and report rate settings, you should see an
   improvement of up to 400% faster response times.

   NOTE: You must download the new version of VTSETS.ZIP which contains
   specific support for installing and using this driver. If you are a
   registered user, you will receive a free update disk in the mail.

VTABLET.DLL (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1. NEW: This driver has been updated to work with the new enhanced mode
   windows driver, VTABLET.386. The tracing interface has been updated.

VTABLET.SYS (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1. FIXED: This driver has been updated to work with SummaSketch I
   tablets and restores their double-click capability. There are no
   other changes.

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1. NOTE: Previous versions of VTEDIT.EXE (prior to version 1.11) are no
   longer compatible with the Trace Command in VTABLET.DLL. Tracing
   will work but the cursor is glued to the left axis. Download and 
   install both VTABLET.DLL and VTEDIT.EXE from VTEXES.ZIP.

########################################################################

                              VERSION 1.10
                            ================
                            (March 26, 1992)

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: A toolbar now joins the status and scrollbars to assist you in
    navigating the Editor's window. It contains miniture icons for the
    twenty-two most commonly used commands. Check it out!

2.  NEW: Style labels now automatically wrap to the object's bounding
    rectangle except when exporting to a metafile or using the Greek
    Fonts option for either the display or printer.

VTABLET.DLL and VTABLET.SYS (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1.  NEW: Sixteen button cursor support has been added joining stylus
    and 4-button cursors. As with all virtual tablets, only four
    buttons are actually ever used (this is a Windows limitation).

2.  NEW: Button handling has been improved for applications which
    require simultaneous presses and releases of multiple buttons.

3.  NEW: Kurta IS/ONE tablets for 8.5"x11", 12"x12" and 12"x17" have
    been added. See DIGITIZE.TXT for their configurations.

4.  NEW: The choice of absolute or relative positioning has been added
    to the Windows driver and Control Panel applet running under
    Windows 3.1 or higher.

5.  NEW: Report rates can now be configured. Under the Windows driver,
    an 'AutoEnhance' mode switch automatically lowers the tablets'
    report rate when running under Enhanced Windows to boost total
    system performance.

6.  FIXED: A bug in SummaSketch I (not II) tablets results in loss of
    double-clicking under Windows and DOS. This problem has been fixed
    in Version 1.11. Download VTSETS.ZIP and VTEXES.ZIP and make sure
    the new enhanced mode driver is installed.

########################################################################

                              VERSION 1.01
                            ================
                            (March 16, 1992)

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~

1.  FIXED: Build problems have been noted with deep cascading menu
    structures resulting in template regions that are too small for many
    output devices and are also capable of producing a crash in the
    Editor. This problem has been fixed in Version 1.10 which now warns
    you and asks to continue.  Answering 'yes' will build a template for
    the menu but skip the 'menu items/template regions' in question.
    The workaround for earlier versions is to turn off cascading menus.

VTABLET.DLL and VTABLET.SYS (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1.  FIXED: Problems with certain SummaSketch tablets have been fixed in
    Version 1.10 which occassionally caused the tablet to hang at
    startup or when switching back from DOS under Enhanced Windows.

########################################################################

                             VERSION  1.00
                            ===============
                            (March 9, 1992)

SETUP.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~

1.  FIXED: A problem installing VTUSEREG.DLL from other than a root
    directory has been fixed (1.00A). Download the new version of
    VTEXES.ZIP or run SETUP.EXE from the root directory of your fixed or
    floppy disk.

2.  NOTE: If you are installing the Interface over an existing
    digitizer driver under Windows 3.1, you may receive an error
    indicating that VTABLET.DLL cannot load because the comm port is not
    installed. Under Windows 3.1, the mouse driver may block the port
    from access by other applications (including SETUP.EXE). You must
    delete or comment out with a semi-colon (;) the line in the [Boot]
    section of SYSTEM.INI that reads 'mouse.drv=' before running
    SETUP.EXE. You can also try running SETUP.EXE again after restarting
    Windows (VTABLET.DLL should be installed at this point) or try
    installing VTABLET.DLL manually.

3.  FIXED: Manual loading of VTABLET.DLL in [MMCPL] under Windows 3.1
    was incorrectly stated in the READ_ME.TXT. The CONTROL.INI file has
    been changed from the Final Pre-Release of Windows 3.1 to the Final
    Release. Consult your final Windows 3.1 documentation for the new
    location of the [MMCPL] section and how it works.

VTEDIT.EXE (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~

1.  NOTE: Scrolling the Editor's window quickly in Windows 3.0 without
    allowing the screen to repaint fully can result in a haphazard
    display. This is due to a bug in Windows 3.0 which was fixed in
    Windows 3.1. The workaround requires scrolling slower, i.e. waiting
    until the screen is painted before clicking the scrollbar arrow
    or pressing a cursor key again. Alternatively, you can scroll
    quickly and issue a Redraw command from the View menu (Ctrl+R).

2.  FIXED: Build command problems have been noted with applications such
    as CorelDraw, AutoCAD for Windows, Ventura Publisher, etc. where
    menus comprise bitmap images or cascade to deep levels (and no
    error message was given!). The workaround requires unchecking the
    Cascade Menus option in the Build dialog box. This will work for
    cascading menus containing bitmaps (CorelDraw) but not for top-level
    popups (like AutoCad for Windows).

    This problem has been fixed in Version 1.01 (download VtExes.Zip)
    along with an error message if the Build fails. Bitmap menus are
    now ignored since they have no keyboard interface unless supplied
    by the vendor (see vendor's documentation and draw them manually).

    Note: The maximum level of cascading menus permitted is 3 counting
          from the menu bar. This is because the resulting regions can
          become too small to distingish visually on screen or by hand
          on the digitizer's surface. Also, the maximum number of
          regions currently supported is 256 which ''could'' become
          exhausted by deep builds on cascading menus. Finally, the
          maximum number of items per menu is 25. Beyond that they are
          truncated after asking you if you wish to continue.

3.  NOTE: Build problems can also occur on Multiple Document Interface
    (MDI) applications, such as Word for Windows 2.0, if the build
    command is applied before the application is opened or it's menus
    accessed. This is because some MDI applications wait to initialize
    their menus when first accessed and cannot be scanned correctly by
    Build (which now builds them anyway). Open the MDI application and
    roll the cursor across the menu bar dropping down each submenu
    before using the Build command to work around this.

VTABLET.DLL (VtExes.Zip)
~~~~~~~~~~~~~~~~~~~~~~~~

1.  FIXED: Some problems have been noted using multiple instances of
    VTABLET.DLL loaded as both the mouse driver and an installable
    library under the final release of 386 Enhanced Windows 3.1 when
    other interrupt driven devices are present and a DOS window is
    closed. This has been fixed in Version 1.01 and the workaround
    simply requires loading the library in only one configuration, ie.
    mouse, library or pen tablet. The functionality of the driver is
    not affected in any way. If you are not sure how it's loaded under
    Windows 3.1, check the control panel for multiple icons - if more
    than one - and change SYSTEM.INI accordingly.

2.  NOTE: Templates work fine under Window 3.0 but the cursor will
    not respond unless VTABLET.DLL is the designated mouse driver.
    Under Windows 3.1, VTABLET.DLL can manage the mouse cursor in
    conjunction with another pointing device (like a mouse) even if not
    designated as the mouse driver. Check the 'mouse.drv=' entry in the
    [Boot] section of SYSTEM.INI to see if VTABLET.DLL is the mouse.
