SYMPTOMS
========
If a TSR (terminate-and-stay-resident) program loaded before Windows (a global
TSR) is used to create a pop-up window over the Windows display, the display
will be disrupted.
CAUSE
=====
When a global TSR pop-up window attempts to overlay the Windows display, the
pop-up places the system virtual machine into text mode, which disrupts the
Windows Virtual Display Device (VDD). When the pop-up is complete, the display
is not restored properly.
RESOLUTION
==========
Global TSR pop-ups are incompatible with Windows. The same functionality should
be written into a Windows-based application.
