include/exclude crashing Max

[Furnace]

Hi,
Has anyone worked a way round this problem, Max crashes every-time I add an include/exclude to a VRay light or MultiMatte include/exclude?

Thanks in advance for any advice.

What are the V-Ray/3DSMax/OS versions and service packs?
Does the issue occur on every scene or just on particular one?
Can you try it on completely new scene with a few basic primitives and light/mm-element?
