recently upgraded Vray to 1.5 and getting weird crashes

I have recently upgraded Vray from RC to 1.50 SP1 on my 32bit Max 9 SP2.
I
In a scene I’m working on, when I create a Vray light and move, rotate or edit it, max will just shut down. I’m not rendering or anything!

Anyone any idea what’s going wrong?

If I try a new scene sometimes it crashes, othertimes it doesn’t but everytime I work that that particular work scene, it will crash. It’s infuriating cos I cant do any work on it.

Any ideas?

There is no difference in the display code for VRayLights between RCs and the final. However, you can try to update your display drivers; if that does not work, you can try to switch 3ds Max to another viewport driver (e.g. OpenGL) and see if it helps.

Best regards,

Thanks for the suggestion. I downloaded new drivers and am running max using Direct3D drivers - and the problems been sorted.
