OMG, you have no idea how much I love you! I was having the same blank window startup problems (seems to be a Java thing, BTW, not just Limewire) and tried everything: Re-installing Java, deleting .limewire folder, re-installing Limewire, updating drivers, etc, etc...

Now all I had to do was stick AA and AF on Aplication controlled and it works again!!!

What a complete and utter star.
