I agree. Can you tell that I don't either? I'm learning though. :-)

Ah... I should've seen that coming :-(

I *think* that by calling LOADCT in this instance you're actually
specifying every single colour as a 24-bit value. Which you can't.

Off the top of my head, I'd try defining my colour table before
changing device, and then seeing if POLYFILL and COLORBAR accept the
TRUE keyword. Don't have the time to check this right now, sorry.

I'm sure David (most likely) will be along shortly with an explanation
of how to solve your problem in a much more sensible way, and will do
so more eloquently than I could - even if I knew how ;-)

Good luck!
