Re: [PyMOL] Problem with coloring of sticks

Hi all,

Before I go out an buy an ATI video card to test/debug this, can
anyone else verify that this error occurs on the 965G or other desktop
card?  The 965GM, I think is a mobile-only card.  If someone is
experiencing issues on a desktop box, please provide me with the exact
setup.

Cheers,

-- Jason
