Thanks for the info.
I will check and eventually try to reinstall Limewire but i have only 1 user and have not tried to lock any permissions.
What is strange is that although Limewire is installed in the "general" applications folder (and not in my "home/app ..." folder), the prefs are stored in my "home/lib/pref ..." and not in the general "lib/prefs ..."
