PV crashing when applying materials

I am experiencing problems with photoview.

With certain assemblies big and small my photoview crashes andsays:

the instruction at"0x0037c207"referenced memory at "0x05100200" thememory could not be "read"

this occurs when i apply certain materials for example "painted=> dark powdercoat" to certain assembly's. The materials thatcause the crashing differ from assembly to assembly.

I don't think its a performance issue because i worked with thesame materials on much more complicated assemblies without anyproblems.

Does anyone have the same problems as I have and hopefully found asolution to them.

thanks in advance,
