SYMPTOMS
========
If more than one virtual machine (VM) runs the Microsoft mouse driver in 386
enhanced mode, the mouse driver for the additional virtual machines returns
error messages. In some cases, when you return to Windows, the mouse stops
responding (hangs).
MORE INFORMATION
================
Steps to Reproduce Problem
--------------------------
1. Start Windows 3.0 in 386 enhanced mode without an MS-DOS-level driver present
(that is, without MOUSE.SYS or MOUSE.COM).
2. In the Program Manager, start an MS-DOS command prompt. At the MS-DOS command
prompt, "type mouse.com" (without the quotation marks) and press ENTER. The
Microsoft mouse driver displays the message "Mouse driver installed."
3. Type "exit" (without the quotation marks) to return to Windows. Windows then
sends a message to the MS-DOS screen about "Windows Pop-Up Program Support."
4. In the Program Manager, start an MS-DOS command prompt again. At the MS-DOS
command prompt, run MOUSE.COM again (see step 2). The Microsoft Mouse driver
displays the message "Driver not installed -- interrupt jumper missing."
5. Press ALT+TAB to return to Windows.
The mouse is frozen.
6. Press ALT+TAB to return to the MS-DOS command prompt. Type "exit" (without
the quotation marks).
You can now use the mouse again.
7. Repeat steps 4-6.
The mouse is frozen again.
