Hmmm I have a similar setup but haven't encountered any problems. And I usually have my Firewall, Netscape Mail and MSN Messenger running in the background too. I bought Tweak XP Pro 4 not so long ago and it's really good for managing the memory. When I run it I am often surprised to discover I've got 500+ MB already in use that needs remanaging.
