I think I've got it.  The timer event to draw buffered graphics to the
screen was being triggered after the graphics window had closed, and
was getting a junk bitmap handle to work with.  I've patched devga.c
to prevent this, and it seems to work here.  I need to do a regular
(non-debug) build now and make sure this doesn't break something else,
then I'll commit the change.
