Thanks Directrix. WebUI works just fine but it happens that µTorrent stops answering by unknown reason -- i can see only "Loading" all the time. µTorrent works well (no error messages or anything of the kind) but i can't communicate with it. Source machine: MAC OS X 10.4.7, Intel Core Duo, Mozilla FireFox (the last). Destination machine: W2k pro SP4, µTorrent and WebUI 1.6.1 b481 Thanks.
