Sadly you get the feeling that Buffalo doesn't care about normal end-users.
I just looked through the Idea Lounge, and if you take every request concerning Utorrent together (request for Updates or features from newer Utorrent Version) you get at least over a 100 Kudos.
It should be more, but i believe that nearly no one knows the Idea Lounge System.
At least i didn't know about it till it was pointed out to me.
My Idea für the Update to a stable Version of Utorrent only got 18 Kudos, since i postet it nearly 6 weeks ago (one even from a MOD).
Maybe Buffalo wants us to change to their competition?
At least drmemory is trying to help us.

Thx for the Info, from that it looks like Buffalo likes to use BETA utorrent clients sind the B in UE210B stands for BETA just like in UT300B.
Maybe our only chance for a clean working torrent client is, like Hooner said, to root the Station and install our own client....
