I had uTorrent and had the same problem. Switched to BitTorrent and it still happends and I can't find out what it is. When I open the program, it runns ok for a few minutes up to maybe 10 minutes then it stops responding and I have to close it and open it again and the whole process repeats. This way it takes FOREVER to do anything with it. I saw something about certian things on my comuter that may not be compatible but I don't see what it could be. Please help.
