Requires Python 2.6 I'm afraid.

Not sure why that slice isn't valid in 2.5 yet - haven't had time to investigate.

Thanks, that solved it. I never thought to try 2.6, because this isn't the kind of thing one expects it to make  difference about.

I looked into this a bit, and I think it might be a difference in ctypes between 2.5 and 2.6. The type of the object in question is <class 'pyglet.graphics.vertexattribute.c_ubyte_Array_800'>. It seems likely that ctypes arrays didn't support slicing before 2.6.

Yeah, that's what I figured. Thanks for confirming it.
