What version of Limewire are you using and what version of Norton? As of a few days ago, I realized having both current versions may not be such a good thing. The solution? Disable all Norton related items (except Personal Firewall if you're on DSL) in your Extensions Manager (in my case I did it in Conflict Catcher) and save that set as something else (I called it "Limewire"). Voila--I have no freezing problems whatsoever. Only thing I get are occasional Type 2 errors. In my case, I have a lot of stuff in my Mac and I need more RAM. Granted, I use an earlier version of Limewire (2.5) and could probably run it in the latest version with Norton disabled but I'm going to keep my current setup since I haven't been able to get Limewire to work for a few months. I'm using a G4 Mac, OS 9.2.2 with the basic version of Limewire.
