My biggest complaint is that they slow down and sometimes freeze my computer, especially when I'm printing a document and one shows up, or when I'm running Limewire in the background while I play a video game. They won't let me click on any of the Limewire tabs until I get rid of them, either. What I'd like to know is how the heck to shut them off; has anybody figured that out yet?! I never had this problem before last Wednesday when my computer crashed and I had to reinstall everything from scratch.

And if somebody is using this program to steal my passwords, through tracking my keystrokes or whatever, then I don't care if it IS the only good file-sharing utility for Macs, I'll drop it in a heartbeat.
