Nice grads Bruce. Well I do see quite a bit of banding in the grayscale
grad, though it is like C. David said "tiger stripe", as opposed to the wide
and obvious. It's curious that it shows up more strongly in some colors
(YGC) than others (BMR) for me. So is this a common malady of monitors, and
is there a cure? I have a Lacie Electron 22 Blue, Mac G4 w/ ATI graphics
card, 16meg VRAM.
