wine 1.1.29 and utorrent 1.8.4 (build 16381) are working fine for me. I've had no problems since using the workaround for 1.8.3 mentioned in this thread: http://forum.utorrent.com/viewtopic.php?id=58864
opened a ticket for this one: when highlighting more than one torrent, and applying a label, it applies the label to the last torrent in the list. none of the other torrents get a label. tested in firefox 3.0.1 and IE 7.
