The same thing was happening with v/2.2.2(1?).
Running OS 9.2.2 on a Titanium w/512k RAM, if I click into the Mac menu bar directly from LimeWire, the program exits with a error type 2. If I make anything else active first, including the Finder, it works fine. Forget just once and the program exits and all heirarchical menus under the Apple menu disappear. The only way to run LimeWire again is with a system restart.
