A very resourceful person(s) has been able to find the reasons & solutions for this problem. I will include some links to the main threads in question.

The easy fix for Limewire popping up every few seconds (try this first) (This may or may not work for everyone but is worth trying 1st. After that go to Norbie's site or try suggestions in posts above.)
