Which spyware/adaware app did yo use to detect that? I'm aware of at least one that doesn't work properly! It find them in apps & places where no other does, why b/c it doesn't work correctly & gives you a false sense of security or bother. Apparently LW did have some traces that were removed in late version 3 or early 4 I can't remember. Perhaps you see here in LW's version history: http://www.limewire.com/english/cont..._history.shtml The Pro version doesn't have the update to pro window when you 1st open LW.
