Hi Warren! I tried the new features of PyMOL, my OS is WinXP Pro SP2 and my graphic card an ATI Radeon 9700. The "draw" command runs without any problem, of course I tried to go above 4096 pixels :-) and PyMOL rescale the values to fit 4096. It's really fast and I love the white frame around the structure and the label for the screen size. I exported the image with the png command, and here as well no problem.
I also tried the "set sphere_mode, 5", amazing!! It looks very nice; unfortunately I couldn't test it on large systems because I have nothing like this on my computer! But I noticed that the transparency feature doesn't work any more (set sphere_transparency=0.5 for instance). I could restore the transparency by going back to the "normal" sphere_mode=-1 Well done Warren ;-) Cheers, Greg.
