Hi David,

Your first message only just came through, perils of usenet I guess...

Indeed running cgLoadCT twice, the second time without the RGB_Table keyword seems to have solved the problem.

If you're up for it, I'd still appreciate you (or anyone else for that matter) having a look over the code I just uploaded. I suspect there are a number of unnecessary calls in there that might be better replaced by some of your latest CG calls? I for instance just saw that I'm using the TVLCT call in the beginning, which serves no purpose any longer?

Many thanks!
