I am also having trouble with limewire 4.0.7. After a while the downloads die down. The I am beeing informed that it appears I have no connection to the internet. Then I can't even browse. There seems to be something eating up all my bandwith.

I stopped Limewire but to no avail. And if I try to "kill" the javaw process, it won't die. The only option - reset.

Pretty lame if you ask me. This version should be called lamewire. Just my 2 cents.
