Try uninstalling it, reinstalling it, turning off the fax and STP extensions that came with the MRJ package that lime wire uses, adding more ram, the limewire ppl suggest at least 64megs. It works...It used to crash all the time when I tried to click on the apple menu but I increased the ram and now it's all good except for the frigging "please insert zip disk" dialogue box that pops up all the time. I'm on a g4, 512 megs RAM btw
