My experience is that when I've had such problems, they are related to
DirectColor graphics.
HELP, /DEV
should tell you whether you are using TrueColor or DirectColor. You
want TrueColor. Usually,
DEVICE, TRUE=24
should solve the problem (as the first command before any other
graphics commands!), but also I assume you are using DECOMPOSED=0.
