Aren't we all. ;-)
The problem might be related to the fact that the Nvidia driver comes with its own openGL libraries -- you have to make sure that applications use these, not the ones that came with the distribution. The README that is included with the Nvidia driver will tell you exactly how to check this, and how to correct it if necessary. (It is available online too, btw.)
Hope that works for you!
