Actually I always defrag weekly whether I need to or not and get rid of incomplete files,etc. it was only limewire that ran slow like this and had problems with no response or slow response when clicking. I also tend not to run any other programs while I'm in Limewire either. I just upgraded to Limewire 4.14 last night. I think the other version I had was corrupt or buggy. maybe this upgrade will work but from what I've read in here, this one will be slow too. Maybe limewire is an energy hog. ughhhhh!
