I think it's Forrest who's got the 4GB RAM, not I. =] I've got a Mac Pro with 2GB RAM. Activity Monitor shows that OW uses between 75 and 500MB real memory (the longer it's running, the more it uses). I tend to keep things running smoothly by quitting the app every time I get up from my desk and just relaunching it when I return. I also try to regularly perform maintenance, clearing things which might slow it down: flushing the cache, clearing history, etc.
