Sorry, I don't have any good ideas. I think the research group somewhat accidentally stumbled on the answer to their question. I guess a possible area of concern is anything having to do with the graphics driver, or OpenGL. It's probably diagnostic of something that you have these problems with both Python 2.5 and 2.6, since one would expect differences.
