After installing and uninstalling and re-installing both Limewire 4.0.8 and java numerous times, I had no luck fixing pro's instability on my comp. It would spit out numerous error codes, lock-up, crash, etc.
It was horribly unstable, it would work, sort of, for a few days then take a nose dive.

But I discovered, while trying something else, that clicking on Limewire.jar INSTEAD of Limewire.exe launches the program and it works perfectly! Why should that work?

Now it works great as long as I launch the .jar instead of .exe. strange.

(p.s when it was unstable, the text in some columns were out of alignment and the options window would open without the "apply" buttons visible)
