Using 16407 on Vista, I have some issues with hanging at the speed guide. (note, the first two dumps uT had a dll from rklauncher in it). First hang, when I tried to run the speed test I got Data send error 10053, and then the program froze, had to kill it. Second hang, speed test was successful (...I think), but when I tried to close the dialog without saving the settings µTorrent hung again. Third time, I got Connection closed in the speed test area and µTorrent hung. Fourth is Data send hang with uncompressed build. I also experienced a data send hang two builds ago, didn't extensively test the last build however. http://www.mediafire.com/?sharekey=dd096a9fc74eefe095af63b7d44918aa8fab867d78d8cc0c
