What kind of a program was this application?  A VIO program I coded was
still running when this "shudown completed" box appeared.  I
added a thread to beep regularly to detect the moment of program exit and
it was still beeping (until I flipped the big red switch ;-).

This is certainly not true for VIO programs.  I switched to a PM program to
get a WM_CLOSE message and this is AFAIK the only possibility to detect a
shutdown.

I would, however, still prefer a solution for a VIO program and if you
managed to handle this please point out which way to go.
