So far I have liked the beta product quite well. I have had the same issue as above, but on a different platform.

SuSE 10.1 with LimeWire 4.11.0 and Java 1.5.0_06.

Not consistently, but once in a while as I am using Limewire I will lose 'focus' on the window. The interface appears responsive (progress bars move, searches continue to retrieve new items, etc...) but mouse and keyboard do not work. (Sound keeps on playing as well).

No idea what the problem is.. but alas it is there... and that is also why *they* call it a beta.
