I have the exact same problem; I can get to the ToolTips, but it then disappears. Ick. I tried leaving the tooltips open, but it just crashed after about 30 seconds anyway. Running MacBook Intel 2.0 gHz, OS 10.4.7.

Maybe it's an Intel thing? I know a couple of other programs aren't working for the Intels quite yet.

EDIT: On a second look, there's no crash log for limewire, but there is one for it in the java crash log...
