Deluge
Hi. I'm running from a Fedora13/Gnome box with Deluge 1.3.0 compiled from source. First off, I'm really impressed with the libtorrent engine, as a longtime user of Wine/uTorrent, libtorrent seems to perform much better!
However, it seems if I do any 'playing' with the GUI for any amount of time, either the Deluge network statistics will stop being updated, or System Monitor indicates that Deluge starts hogging all of the CPU time. Note that libtorrent appears oblivious that the GUI is experiencing problems and continues happily doing its stuff in the background. The only way to rectify this is to close & restart Deluge...
