Hello, I registered just to post a bug. I'll get straight to it. In build 13910, after downloading TWO heavily seeded torrent overnight (and the download is still running the next day), Firefox refuses to let me surf the web. However, I still could surf the web through another computer on the network. So I went and checked Help>Statistics under utorrent. I found out that the half-open connection is 8.... it might be related. I came to the conclusion that it is at fault. I'm still doing tests though, now I'm running with 50 max half-open connections (windows' default is 10 I believe, so I'm not sure why it failed to let me surf the web). Btw, my mIRC is running at that time and there's no lag for mIRC at all. Settings were 100 connections per torrent and I'm running cFosSpeed. I'll report back in an hour, that should be enough to saturate the connection I guess...
