You cant blame hardware when it works fine for other apps on the
system..........<does this system have this problem constant with
other apps?> if your answer is no then the code for the app
is substandard.

I think this is common on machine with little processor left,
things like firewalls, virus scanners and networks like IIs
use alot of threads and take a mighty processor to allow
other apps the time for things like redraws and such especially when
your code isnt built for speed..

my theory is to double buffer images and hold the amounts of
controls to a minimum on one client at a time..createing
multiple dialog boxs are important for user interaction that allow
clean, fast, smooth operation...
