OSX Slows to a crawl
 

I am aware that Limewire for Mac OS 9. will work in classic mode but doesn't anyone know why Limewire Pro slows OSX (10.2.4 in my case) down to a crawl. The computer is basically unusable while Limewire is running, connected to the Internet or not! Surely there is a reason. OSX is in itself much slower than 9 was but I have not seen any other app drain the system as does Limewire Pro. Any help would be appreciated
Thank You!
