My PC:

Vista 32bit SP1; zone alarm firewall free 8, AVG 8.0 free; bitcomet 1.10.

The problem is that bitcomet, like other torrent clients use nearly 100% of processor; but the process bitcomet.exe itself uses avarage 25%; and there is still free processor power; but system is running so slow that it's impossible to do anything, even mouse is "jumping" ;(

J've searched sollution for this issue, even sent 2 mails to support, but they of course didn't respond.

PC details:

E6300 1,86ghz (if it's running at 2,8ghz the problem isn't solved)

3GB ram; x1950pro
