[Chimera-users] chimera startup problem

[Greg Couch]

Just a FYI to the list, the problem here was an ancient OpenGL graphics 
driver.  Upgrading it made the problem disappear.

I'll be adding an entry to our Graphics Driver bugs web page, 
<http://www.cgl.ucsf.edu/chimera/graphicsbugs.html> with a few more 
details.
