Try these things:
1. Delete the LW prefs folder whilst LW is closed. Found here /Users/your_username/Library/Preferences/LimeWire

2. Tip: Purge the Downloads Queue!

BTW are you sharing from external drives?

It seemed to work, and like a knucklehead, gee why don't I try to find some of those obscure tokyo garage bands from the 70's.... bad ideal.... more zero download files.... purged again, we'll see what happens.... I'm going to back off a bit on the searchs.

I am using an external HD for both my download folder location & shared folders. What would happen if I moved the application there? Can it run from there or does it need to be on the same HD as the internet link & the OS???

When ever I use LW, all of the other internet things SLOOOOOOW WAAAAY down.... so I generally set up searchs and go too bed.... kind of like fishing at night and waking up too see what I've caught....

Thanx for the help....
