Thanx babe. I had done it right after all. I was incrementing by the
wrong type of pointer (DOH!).

PS I got the textured primitves I was having trouble with, working as
well. I forgot to multiply the image.pw by the number of texels per
pixel, so my u, v mappings were all buggered. (Double DOH!). Any way got
to go ...

Luv, Ugs and buckets of poo
