Viewer 3.0 persistently crashes out on my biggest machine 8(. Is it an Nvidia issue? This is a Dell t7400 with 2 auad core 2.0 Xeons, 12GB of RAM and 64 bit Win 7. The login *sometimes* finishes; other times it says that the NVidia driver (latest release, 280.something) has lost contact with OpenGL this-or-that and has restarted. After the GFX driver restarts; no SL executable. What do I do next?
