Are you sure it's the fault of TrueColor/acroread and not some fault in
X driver? I use TrueColor and acroread 4.0 without problems on my
laptop, also 
running RH6.2. 

I am running XFree86 4.0 (no choice, there is no driver for the Rage
chip in 3.3.6). Maybe this could be the difference.

One solution is to start up a second X server running in 8 bit
PseudoColor for
IDL graphics. This would entail switching between servers for your IDL
"normal" displays. It's a solution I have used when I've needed an 8 bit 
display and have not wanted to restart the X server.
