Been away from MS for a while - now I get this - any ideas?
It's a MS solids model although made in AECOsim, currently 08.11.09.829. I downloaded the latest (863 or something?), got this, uninstalled, went back to 829 but still same. W7 64. People have said this can be an Nvidia driver problem - I updated to the latest, 341.95 for my Quadro FX580, but still same.
