Is the TP7 in full-screen or a window?
Has focus been changed between windows?

    Under OS/2 Warp 4, A full screen TP7 IDE can lose its connection to the
keyboard if focus is switched between windows, or a DOS program is started
while a full screen TP7 is running a program in the background.  Mouse still
works to close down via file menu, but this can be extremely frustrating!

    It is possible XP suffers a similar reaction when the 'BIOS' routines get
relocated by the Operating system.  (TP7 saves the IRQ vectors at startup
but the O/S later shifts the routines elsewhere.  Result is a 'pointer to nowhere'
error when TP7 requires the routine.)
