Couldn't find anywhere to report bugs for this portable app. So let me just mention it here. Feel free to point me in a better direction for bugs on this app or just move it to where is is more suited if you are an admin.
I noticed that every time I logout of windows (7 - 64b) and thus let windows close Qbittorrent Portable (QBP), the next time I log in and start Qbittorrent Portable again (shortcut is in the startup dir) it tells me that it wasn't closed properly and that I should restart it manually.
Doesn't seem to actually close unproper. That screen comes up with a few apps win is closing QBP has a note of closing connections or something of that nature then disappears from the list, a moment later the rest is closed. Everything seems proper.
