Isn't there an interrupt listed in Ralf Brown's list that allows a DOS
app to detect when Windows has switched it away?  (Not that it worked
when I tried it.)  I mean, if I could just switch into text-mode when
Windows put me in the background, and then switch back into graphics
mode when I was placed into the foreground again...that would solve my
problem I think.

Thanks for the reply though.
