Ron, This appears to be a Windows specific problem. I can view spheres with 1bgy.pdb just fine under Linux (albeit 168 MB of RAM...), but it blows out on Windows.
However, if you lower the sphere_quality (which only affects OpenGL quality), it holds together: load 1bgy.pdb set sphere_quality=0 show sph ray My suspicion is that PyMOL is trying to allocate a larger block of RAM than Windows can give it in order to hold the sphere graphics primitives.

The same scripts work for smaller proteins, so I'm guessing I need to find some way to increase the memory allocation for the image, or something of the sort. Anyone have any ideas? BTW, I'm using the win32 build and one of the files I'm having problems with is 1BGY, (the cytochrome BC1 complex) Thanks, _____________________________________________ Ronald L.
