The program sorta hangs for me... I can still click around and open menus and stuff, but after about 10 seconds my download rate and upload rate freezes. Like the UI is still working but the guts to the program crashed. Also, once the program hangs in this fashion it will let me apple quit it, however it never really quits. I have to force quit it. -Snow Leopard Oh, and thanks for making a mac version! I used to use transmission but it never worked right on my mac.
