Make sure you have a line like:
device,decomposed=0
in your startup file. Or, enter it at the command prompt prior
to doing anything with the very first graphics window.

This is getting to be a bit redundant, isn't it? I have
a modest suggestion: Why not make Device, Decomposed=0
the default and let people who want true 24-bit color set
it by typing Device, Decomposed=1. Then people going to
24-bit color for the first time wouldn't be so darn
confused all the time. :-)
Try this:
IDL> Device, Decomposed=0
Your Windows machine is set up in 16-bit or 24-bit color.
You will want to learn a little about what that means to
you. Lot's of good information about colors in IDL on my
web page. :-)
Cheers,
David
P.S. An alternative to XLOADCT is XCOLORS from my
web page. It is just a little bit smarter than
XLOADCT (although I see that XLOADCT is catching
up a bit in the newest versions).
