I'm running the most recent µTorrent 1.7 beta build on Vista Home Premium, I have a D-Link G684T wireless router and, as you will see, UPnP port mapping works for me... .. and tho why it remaps it every 20 minutes is a mistery to me, I don't worry 2 much about it coz as far as I can see, everything is OK and 'green' Greetings from a satisfied µTorrent user from Croatia! On a bynote, I'm a busybody and I hence discovered that trying to dump memory info on the logger tab crashes the client. Not going down that road again
