I just installed Rhino 4.0, hoping to (at long last) realise my dream and learn NURBS.
But when I fired it up, the viewports randomly became black and displayed glitches.
Graphics card is Geforce 7900GS 256MB slightly overclocked by BFG tech.
I'm also running on Vista Ultimate 32 bit, and I've heard that Vista causes some issues with the OpenGL in Rhino.
So how can I fix this glitch? I'm not particularly in a mood to install Windows XP -___-"
