I've just submitted a modified version of the sleep desk accessory to
net.sources and info-mac.  In this version, an apple moves continuously
around the screen.  I've noticed that on my 128K Mac at work and my
512K Mac at home, that when the apple moves to a region about the upper
middle quarter of the screen, it starts to flicker.  The desk accessory is
call 30 times a second, and doesn't flicker outside this region on the
screen.  Anybody know why?
