Mac users: We lucked out and obtained a little help from an off-duty Apple engineer today who figured out how to work around the issue in 10.4.3. It was one of these combined bugs -- we weren't doing things sensibly in PyMOL, and the ATI driver wasn't quite complying with normal OpenGL behavior with respect to screen updates.
They changes seem to have done the trick, so I have posted an updated MacPyMOL build at: http://delsci.com/beta Please let me know if this does NOT solve the issue on your machine. Also, since I had to change the lighting and draw-buffer code, please let me know right away if anything strange or new surfaces. Cheers, Warren -- Warren L. DeLano, Ph.D. Principal Scientist .
