Does anyone know a way to determine from an app if the screen is
currently displaying a full-screen DOS session?  (Of course I'm talking
386Enh here, since in standard mode a winapp wouldn't be running at all
while a DOS session was on the screen.)

Bonus question:  Can anyone guess why a program in a PeekMessage() loop
(which is yielding control) would go through the loop several times more
often when a (non-exclusive) DOS session was full-screen than when the
same DOS session was windowed and in the foreground?  (And no, the
PeekMessage loop isn't doing graphics or anything like that...)

Any help would be greatly appreciated!
