I've got 2003 here too.. weird how the memory drops from 26 MB to 4MB when closing the UI. Then it goes back up again to ~20MB. I had some other problems here too with rss feeds i guess.. when i disabled a couple of rss feeds (the ones that i hosted on the same pc) uTorrent wouldn't go up to 50% cpu (dual-core) and unlimited memory use anymore. I still need to test which one of the rss feeds it was, and if it's even caused by the rss feeds.
