[PyMOL] Blank screen with windows XP

[Andrew N. <na...@rc...>]

Beginning today, I get a blank screen when I load a pdb file. The program
seems to be running correctly. The file is "loaded", I can even select
atoms in the file. But the atoms are not displayed on the screen (as
lines, sticks, spheres, etc.).
I tried installing a new pymol version with the same results. I've been
using pymol for a few months with no problem, until today.

Has anyone else experienced this problem?
There were 2 windows updates in the last few days. Could this be the problem?

Thanks
