I recognize the lack of memory problem. My primary computer is a laptop right now, so I'm kinda constrained to the 512mb without spending more money and ditching some of the current ram.

When I'm working I can the memory page usage jumps up >500mb so the physical ram is all used up, and things slow to a crawl. The problem is, even after I finish close the files, and purge the history, etc the memory usage stays that high. I have to shut down the application and restart it - a real pain to do every 15 mins.

I'll look into doubling the ram on one of the desktops and switching to that. Thanks for the inputs.
