Greetings Rafi: Have not focused on any speed improvements yet, but I wonder if you know the location where all or most of the advanced settings are described and or debated? I just updated to 3.4 Beta, while running 3.3.2 stable (?) and lost all my settings and in-process torrents. Win 7 x64 SP1 All torrent activity runs on 500 GB USB2.0 external drive. Directories: Dnload Data, Dnload Torrents, Upload Data, Upload Torrents, uTorrent (for all pgm & .dat). I have a shortcut to the external utorrent.exe pinned to the taskbar. After updating to 3.4 the taskbar shortcut took me back to the update process (near the end). Only the new shortcut on the start menu took me to the new 3.4 app (devoid of all my settings and in-process torrents). I did not attempt to use what apparently are the torrent status files in the utorrent folder (need to learn to use that BTeditor pgm-just learned about it today). The updating process knew where utorrent.exe was located, so it should have had access to the settings.dat file in the same folder. I used the contents of my 'Dnload Torrents' folder to restart the lost in-process torrents (but I stupidy forgot to move the old contents out, so I wound up with 2 sets of torrents - arggh!) The installer did copy 3.4 to the updates folder. I need to check if the settings.dat.old file would have been any help in restoring my old settings? I have updated twice before with no trouble. Is the install problem my fault or is it with the installer/updater itself? BTW: running the 3.4.0_30345.exe in the updates folder took me back to the end of the install prrceass as mentioned above. The NEXT update will be preceded by a utorrent folder backup! Seasons Greetings - if that applies to anyone. Doc Chiron
