I also have the problem of my Mac freezing when using LimeWire. I've tried reinstalling and I've just upgraded to LimeWire 2.6 - still causes the computer to hang (required hitting the reset button to restart!).

Most of the time it hangs while loading. Sometimes it makes it thru the load process, and then it crashes> Once the crashes, all user interface is dead. I did notice that Limewire continues to operate in the background (I can see the lights on my cable modem blinking), but the screen is frozen. One other symptom is that the "Connections" tab is not visable and the Connections menu item is grayed out.

Is anyone else experiancing this? Is there a work around?

Thanks,
Tim
