LimeWire disconnects modem in OSX(10.5.1)
 

I've succesfully used LimeWire for months in X, but since recent upgrades to LW2.4.4 and 10.5.1 it seems that after running for a very short period of time LimeWire disconnects my modem.Irritaingly enough neither the (green/red) button on LimeWire nor the status indicator in X indicate that I'm disconnected. The give away is that all downloads measure 0kps. I'd appreciate any help on this one. Thanks, John
