Thanks for your reply, I'll try to explain my sitution better. I am talking Carrara, the setup options only appear if you choose custome (if I remember correctly of course.) On W95 I was able to have 2 shaders open in the texture room at the same time and see them both and drop and drag between them. But now on my NT machine I only have access to one shader at a time in the texture room, although it looks indeed like I do have multiple shaders open for they appear in window menu. When I use the window menu the positions of the shaders I'm working on change as if I had invisible overlapping shaders open, I just can't see them at the same time. Am I making any sense, should I start over trying to explain? Thanks.
