WINDOWS
Summary:
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 application.
