Beta 5.0 - 9 crash

Is Beta 9 supposed to be any kind of stable? It just crash in many different occasions, i cannot even understand what is making it crash.

It crash in startup, or when i import something or when i move the camera, etc. I can make it run for about 2 minutes, then it crash.

I tried 32 bit as well as 64 bit version but is just the same.

Intel i7 950
windows 7 64 bit
Quadro 2000
6 gig ram

Try beta 12. I had some crashes with every version, but fewer with 12.

Thank you, i’ll try.
