Upgrading from 1.8 to 1.81b Build 11903 reset all of the "speed guide" settings. Since I am using uTorrent very differently (lots of slow torrents), this created a problem. The sorting in this build seems strange. Clicking on a column in the torrent window sorts on that column, but in some cases it goes back to the old ordering on the next refresh. I have seen as many as three (up/down) arrows in column headings at the same time. The old behavior was to sort on a column when it was clicked on. Shift+click sorted within the current sort. Shift+click doesn't appear to do anything in this build. The overall operation as a BT client seemed stable. Could some of my problems be that I installed over the old version (instead of renaming the directory and the settings directory)?
