NVIDIA driver 305.93 causing erratic behavior

COMSOL was working great until I got a Tesla NVIDIA GPU. After installing the driver NVIDIA 305.93 I started getting erratic behavior when mouse clicking on the graphics. When I click to highlight a domain a completely different domain gets highlighted. Same thing on boundaries. For some reason COMSOL thinks the mouse is pointing somewhere else on the screen. The behavior is repeatable but unpredictable. For example everytime I click a boundary the same wrong boundary gets highlighted but its impossible to predict which wrong boundary will get highlighted after drawing a new object. There are also domains that I can't highlight no matter where I click on the model.
I uninstalled the driver and COMSOL went back to normal.
Using windows 7 64bit.
COMSOL support hasn't seen this problem before now.
I don't need the Tesla drivers for COMSOL but its not very convenient to uninstall every time I want to run COMSOL and reinstall when I need to use my GPU.
Anyone else have problems with NVIDIA drivers?

There are now three threads on the same issue.

Erik, the issue exists on NVidia driver versions 306.97 and 307.45 as well.

Geoff, have you tried one of those drivers with the update 1 of COMSOL 4.3a?

I can confirm that on my machine at least, with NVidia ODE drivers 307.45, the problem is fixed in Comsol 4.3a Update 1. OpenGL works fine now.
