I'm on Comcast cable, using Limewire Pro 2.3.3 w/ Java. As soon as I connect my overall downstream speed slows from an average of 1100 kbps to 20-100 kbps. When I break the connection the speed stays slow, doesn't pick back up till I shut down Limewire. This doesn't occur with WinMX or other file-sharing apps. Any explanations, suggestions appreciated.
