This and ...which is what I thought. And yet I am certain that RC2 (in my case) is prioritising TCP over uTP and not the other way round. For example, peers that I am connected to begin with uTP but after time revert to TCP on the same torrent, say, after a tracker update. The IP address of the peer is unchanged, as is the port. The vast majority are on UT 1.83+ as well. Stop and restart torrents and/or uTorrent and the connection to those same peers reuses uTP once again. So unless uTP is being disabled 'in situ' this shouldn't be happening, right? Is it possible to be choked by uTP connections thus forcing a switch to TCP? Perhaps that is why stopping/restarting UT eradicates this problem temporarily, even if RC1 worked fine?
