I think Coonass is really Zippy, rejoining the forum under a new name after a layoff of a year or two. I love Vegas, and I am all for getting my problems fixed !! It would be interesting if you could check on your Vista V8 if you could duplicate this memory constriction. I had some rather large JPEGs in the project and after I down'resd all off them the problem went away, but only until I grew my project to this approx 75% memory limit. I have since figured out that when a project loads and consumes more than approx 75% after loading then during the render it is sure to crash at some point. Vista has this little gadget that shows your CPU usage and Memory usage.

As soon as I run Vegas and load up a project, render it, it randomly crashes to desktop. At first I thought it may be my machine so I tested my memory (4 gigs) extensively using memtest 86+ without any problems, ran various stress tests on the entire system for more than 24 hours without failures, so I feel pretty confident that the machine is OK. I have been getting random crashing issues from the get go using V8.
