"when utorrent is open but there are no active connection, everything is fine. but as soon as i start any torrent (even if i use only 10kbs of my b/w - i have 1mbit), my web browsing gets so slow, that the sites time out. what could be the problem?" i still have this problem. please help! btw, i also tried with other bittorrent clients and they work with no problem. but with utorrent .... :-( :-( :-(
