Running Vista 32-bit, was find with every build until 2899, first crashed ~5 mins after, gave me an option to send a dmp log to utorrent and I clicked yes, after I opened again got a Nod32 error so I added it to exceptions and restarted. Got 2 more "uTorrent has stopped working" crashes within about 10 mins after that without a choice to send a dmp log. Back to 2740 and working fine...
