There is a bug that i spotted long ago but forgot about it because there were more annoying bugs. Now utorrent works pretty fine for me and I'd like you to check the following: I don't use uTorrent 24/7. I usually find something to download and after it is downloaded I stop the torrent, delete if from the list and close the uTorrent. So when i press File --> Exit it freezes for about 5 seconds and then exits. The strange thing is that it's not always behave like that. Sometimes it exits fine. Maybe uTorrent does some actions after deleting torrent from the list, so it doesn't allow to exit until all actions are completed. Check this please. And one more thing. Windows 7 allows to change the size of system UI elements to provide the best visibility. For example I have a FullHD resolution on only 22-inch screen, so in 100% mode things don't look really good. So I have a 125% size Thats why uTorrent icon doesn't look well in tray, because i have 20x20 icons instead of 16x16 by default and it is streched from 16x16 to 20x20 As you can see the icon on the left looks fine, because it is 20x20 or higher. So it would be great if you add 20x20 icon or change anything else to fix that problem. Thanks a lot
