i solved my own problem it seems.. i installed JRE rpm for red hat from http://java.sun.com/j2se/1.3/jre/, then after that was successful i figured out how to install LimeWireOther.zip using JRE.. i used this command: java -classpath LimeWireOther.zip install
from the java directory /usr/java/jre1.3.1/bin
it installed fine, no more freezes, seems extremely stable, everything's Great! i hope it works from non root account too, as I installed LimeWire to /usr/local/LimeWire
a great great program!! thanks for it
