Hi Warren, I just ran into a bug with pymol 0.99 rc1 on SUSE 10 Linux on my Acer TravelMate 800, which has an ATI Radeon video card. The problem is that for atoms with negative x-coordinates the spheres don't show up. When I shift the coordinates using alter_state the spheres show up again. This happens with different files. I don't know whether the problem is specific to my laptop. Later I can try it on some other workstations (windows/red hat) if you want. Raytracing still works fine. If you want I can send you an image showing the problem or hand you a pdb file which does the trick for me.
