I modified your program slightly, because I don't have the CBar
program. And, of course, I added Device, Decomposed=0 because
without it you will NEVER get colors anywhere (see posting by
our newest member, S. Daniel Kwak). But my program looks like
this:

pro cbar_true
device, decomposed=0
loadct,3
colorbar
wait, 20
end

And it ran *perfectly* on a Windows NT machine set in 24-bit
mode.

Are you sure you created the save file properly?

IDL> .Compile cbar_true
IDL> Resolve_All
IDL> Save, /Routines, File='cbar_true.sav'

If you forget the Resolve_All command, of course, then you
will never find the LOADCT command and that would cause
colors to be gray-scale.

Cheers,

David
