Just how much RAM and HD space does Poser need? Yesterday trying to render a large file (8 characters) I got the message "out of memory". But this Mac (G5 2.7GHz dual processor) has 8Gb of RAM and at least 100Gb free space on the drive.

This has happened before even with some smaller files, both in Poser 7 and Pro 2010. Is there something wrong with Poser's use of memory? I've heard of something caled a "memory leak" - is this what's causing the problem - any ideas, please?
