    AutoCAD 2002 and Windows XP

    We have a C++ DLL that (via COM, not ARX) allows the user to select and do
    some processing on entities in a drawing.

    Since moving to Windows XP, we have been seeing the following message rather
    frequently:
    "AutoCAD Main Window is Invisible."
    It usually happens after calling AcadApplication.ZoomAll() and another
    application has moved to the foreground of my monitor;
    Any ideas why?
    Thanks,
    Jon
