I have been having many problems with LimeWire 2.2.1. First of all, LimeWire doesn't keep all my preferences all the time. It doesn't remember the number of connections I want to keep it at, and it doesn't remember the servers I connect to either. For some reason I can't ever quit the program. Every time I try to quit in any normal fashion, either with command-q, the File menu, or even control-clicking on the Dock icon, the window just minimizes. To quit the program I need to Force Quit LimeWire. Sometimes when LimeWire is minimized and I select it from the Dock it freezes my computer. This usually happens if I have any other program open at the same time.
