I get this problem randomly as well. Using Poser4.03 with the memory patch. Running a 3ghz P4, 2GB DDR RAM, 2 80GB Hard Drives, 256mb GeoForce 5600 vid card (not sure that matters).

I have tried the CL workaround and find that it works at random. I also only get the error at random. I can render a few images (I'm doing 300dpi and ranging from from 3450x2700 at largest to 1950x1350 at smallest) and it goes fine then suddenly it throws the error at me. Rebooting, in itself, does not correct it which if it was a memory issue you would think that it would.

I usually have to check the computer managed button (or whatever it's called) and hit set, then go back and change it to 10/500 per the CL fix and reboot a couple times and then works for a while.
