I saw a couple posts about this above problem. It is definatly caused by LimeWire. I didnt have this problem until the new 2.* series. I'm currently running LimeWire Pro 2.1.1. If I reboot my computer and don't start up LimeWire I can move, rename, and delete the .mp3's I'm sharing. If I start LimeWire I randomly cannot do the same. It should be noted I only share .mp3's. If I download .mpg's or .avi's I can move, rename, or delete without a problem as I'm not sharing them. Its almost like this new version of LimeWire is keeping the files open when it goes through and checks which files your sharing. Hey LimeWire people, this is a bug it sounds like. Check it out. Thanks.

Sprint.
