Same thing is happening to me. At first uTorrent would assign a random port number even though it was set not to, and when I tried resetting it to the correct port it would beachball and i'd have to restart, after a while I was able to get it to keep the correct port but it won't read it as being open. I restarted my computer but that didn't seem to fix it. uTorrent is definitely a lot slower now, I don't think it's a UI glitch.
