I'm glad this solution in this thread worked for so many, but as for myself, I've had no success so far with the reinstallation of the said security updates SecUpd2005-002Pan.dmg or JavaUpdateMacOSXv10.3.9.dmg. I've done all the trash preference things. I'll keep trying of course in case I did something strange along the way but at this point for the record, LimeWire still just won't boot in 10.3.9 for me. Right now it hangs at "Loading HTML Engine..." stage. Sometimes it doesn't even get that far. Reinstalled LimeWire several times etc. etc.....
