For some reason, whenever I try everything short of Force Quiting, LimeWire minimizes instead of quiting. Not only does it do that, but when it is hidden and I select it from the Dock it freezes and I have to restart.

FYI: A thread entitled "something weird!" isn't going to get a lot of readers or helpful posts. Note that there is only one other response. I certainly wouldn't have read and replied if I wasn't drunk and bored waiting for my girlfriend to get dressed to go out. Try something like "problems with shutdown" or something informative that suggests why someone should follow the thread.
