any thoughts on this one ?

8 lights is sort of few.

OpenGL typically maxes out at 8 lights. However, I wrote some code that should have managed this properly and eased additional lights in and out depending upon observer distance. Evidently, this is not working (anymore).

As David said, we should not enable more lights than GL supports. However, this should not crash - report this to ATI. Also, someone should try this on an NVIDIA board.
