Well, then. You have bigger problems than I thought. :-)

My guess is that you are on a LINUX computer that is
using a DirectColor visual. You can see if this is so,
by typing this:

IDL> Device, Get_Visual_Name=theVisual & Print, theVisual

If you see DirectColor printed out, read this article
IMMEDIATELY:

http://www.dfanning.com/misc_tips/idlsetup.html

As long as you are in DirectColor, *nothing* will make sense to
you. :-)

If this is not the case, send us the result of this command:

IDL> Help, /Device

And we will see what to do next.

Cheers,

David
