So a bunch of people I know have been talking about Konfabulator lately so I thought I'd give it a try again. There are definitely some better widgets out there then when I last looked, but my big problem with it seems to remain. After running for about 12 hours it just seems to start slowing down my system. I'd open up a finder window and it would just lag while doing so.

Edit: I think I found the solution, hopefully this will help.
