Schnurmac, welcome on Gnutella forums
(1) Could you try first to repair permissions on your drive and clean caches:
here
You can also download
Onyx and use this freeware to clean caches
(2) if this not help, download the Apple 10.4.3
combo and re-installed over your existing 10.4.3
(3) even if on my 10.4.2, LW4937 works fine with Java 1.4.2, someone states that upgrading the Java to
1.5 solves problem.
Regards
Philippe
