µTorrent 1.7.6 (build 7859) works just about perfectly for me on Mac OS X "Tiger" 10.4.11 using CrossOver 6.2.1, including the WebUI and FlashUI. If installed in a win98 or win2000 bottle, the background in the torrent list pane is black, setting the Windows Version to Windows XP in wincfg (Control Panel) fixes this and properly displays it as white. No display issues when run from a winxp bottle.
The only thing that seems not to work is UPnP. I have to manually forward a port from my router to uTorrent to make it work properly.
