do you have a swap file on the rartition you're rendering on? I seem to remember a CL technote on the subject some time ago, only affects people with lots of memory. I think it was a P4 issue, but it wouldn't surprise me if it was still a P5 issue too. Can they write a program that works? I guess that depends on Bill "I did not have sexual relations with that woman" Clinton. Meaning, it depends on what you mean by "works" :P later jb
