Bitcomet

I'm using bitcomet right now and since yesterday its acting really slow and choppy. It still downloads stuff but when I open up the window, it never goes back to the start menu bar so I have to do ctrl+alt+delete to shut it off all the time. Why is this happening? Anyone? Oh and does the upload amount affect the dl amount(speed wise. like would I get a lower dlspeed if I set upload speed limit from 100kb to 50kb?)?

Does bit comet have any silly spyware or anything like that? I've heard alot about this prog but I've always been iffy when it comes to P2P
