I tried changing graphics bit size but it did not work. I didn't
think
it would work anyway because I access IDL, which runs on a SunOs,
remotely using RH Linux. Could it be a bug in the X software on RH 9.0? I
did not have this color problem with RH 7.2.

In regards to the Macs has anyone tried changing to an earlier X11
version to see if this fixes the color problem? We can't find the
earlier version. Well actually we didn't try too hard because we want to
know if others have tried first to see if its worth the hassle.

Thanks
