In even further testing I have found that the freezing seems to be happening because the mouse event messages are being captured by the first button clicked. That makes it look like its frozen but in reality the clicks just get captured by the same button and so don't activate anything else. When I click on a different application the event capture is released.

This must be happening in the Gnotella application for some reason and I'm guessing on some systems the magic mismatch of underlying drivers or whatever cause this behaviour to act buggy. I'll keep trying to figure out what it is but in the meantime just clicking on a different application at least un-freezes it for one more click. The Setup tab window has to be first brought up, click on different app and then back to the Setup window and then it is active on all tabs and it doesn't freeze up after that. The rest of the main app. still freezes up as described before until clicking on a different application.

This type of freezing is not related to having to many hosts or some of the other ways that people seem to be posting about.
It isn't solved by the other methods either.
