I had a really strange color table problem on Linux. No matter what I
did, I would only see grayscale colors. In XLOADCT, when I'd mouseover
the colorbar all colors on the screen would flash. As soon as I moused
out the colors outside of the IDL widget would go back to normal and the
colors in the IDL widget would go back to gray. If this is what you
mean by "weird color table problem," I can tell you exactly what to do
to fix it.
