I'm having the same problem as John C: program stalls,"notresponding" in task manager, application window blanks,thenkicks in again after 5-15 seconds. Its more frequent whenusingMasterCAM. I've tried changing the mouse driver, no luck.Alsodifferent versions of the video driver for my NVidia GeForce7600GT (the version specified on the SolidWorks website), stillnoluck. Adjusted the video settings to lowest, still no luck.Theonly thing that works is UN-installing the video driver andusingthe windows default video driver which works butgives poorquality.

I'm really stuck, anyone else using this card?SolidworksAdministration
