Well, I'm not overly fond of using DEVICE DECOMPOSED
in code anyway. Plays havoc with what you are trying
to do, usually.

I prefer using device-independent color methods. Here is
a Virtual Machine test program that uses FSC_COLOR to
load colors. You can find FSC_COLOR here:

http://www.dfanning.com/programs/fsc_color.pro

Do this:

1. Start a fresh IDL session.

2. Compile VM_TEST

IDL> .compile vm_test

3. Type RESOLVE_ALL:

IDL> Resolve_All

4. Save the routines in a save file:

IDL> Save, Filename='vm_test.sav', /Routines

5. Exit IDL.

Now run the save file in the Virtual Machine. What colors
are you seeing?

Cheers,

David
