Funny thing J, for what it's worth, the Performer code still gives me the Magic Number Error if I feed it any texture that is wrong and I know I'm using OpenGL 2.0. So I thought in that case it was a performer thing. Well I’m talking about 5+ year old code at best, that was hacked from something that was designed to run on an old SGI box. God knows what I'm going to get out of it!
