I'm no expert on linux. However, I had my LimeWire freeze on me too. If you installed the LimeWire self installing program as root for example and then try to run it as user1 it seems to hang. I Changed the permissions on the LimeWare executable and this allowed the program to open and start. However ... while I can start the program as user1 now. I cannot download any programs. I can search for files etc. but it doesn't seem to download files. I have tried changing permissions on the directories but this doesn't seem to work. I even tried moving the whole thing to my home directory for user1. Still nothing.
