Alright, here's my dilema, I am presently using Win98 for Carrara. When attempting a 3D Boolean subtraction/insertion/ union or other operation I will get a rendering failure with "A C++ runtime Error...invalid page fault...." message. I would like to know 2 things: a) Does Carrara run better and less buggy in WIN NT (ie should I get WIN NT); and b) Does anyone know of a workaround for the above rendering failure?
