Rendering starts sometimes and then cuts out - but other times just hangs and I have to Ctr/Alt/Del Carrara out. it doesn't matter what rendering settings. I really can't figure out the problem - it's a complex scene - it renders in C1 ok but not in C2. - as a matter of fact - it appears that I can't even get it to render with the raytracers in c2 either. I need to do a bit more investigation into this problem - it's anoying the hell out of me!
