Limewire doesn't install any invisable files. i suspected the same and searched all invisable files...none were related to LW. I did find a preference file " .com.zerog.registry.xml " created by LW which of course would not
show up in a Sherlock search.
I believe the original poster of this thread has multiple problems not related to LW ie; firmware not up to date,MRJ and /or Carbon Lib. not up to date,insufficient or marginal memory...beyond the scope of these forums.
