I'm having the exact same problem (G3 OS 9.1).
I tried w/ LW 2.1.3 Pro, with the newest basic Limewire, and with Limewire basic 1.7. I even allocated 75 MB Ram to see if it would clear up, but nope!
... I also noticed that when I set-up folders on an auxiliary drive to be shared, it completely crashed everything (when just a week ago it was working fine).
Anyone have any solutions?
