I tried your suggestion (thanks!) with the latest 3.2.3, and after about 2 minutes it just froze while doing a search and then "unexpectedly quit". It generated a crash log with over 200 threads.
Don't know if it's this version or because of using java 1.4.1

BTW. You can make the suggested changes using a gui editor by control clicking on the Limewire app, showing contents, and drilling down util you find the Info.plist file. Then you can open the file in your favorite editor.
