Thanks for the best torrent client ever. I'm using Zonealarm free version 8.0.298.000 with TrueVector security for the stealth reason but found a compatibility problem with µTorrent 1.8.3 build 15728 and the TrueVector engine on my system (Windows XP sp3) which leads to the truevector service crashes. Do you now why and are there anything I can do to workaround? This problem did not exist within the previous version of µTorrent Thanks in advance Frogmaster Well - my problem is solved. It's seems something did go wrong during the upgrade. After an uninstall, download and a clean install of µTorrent 1.8.3, everything is just fine - thanks again for making µTorrent
