Stop button still doesn't seem to work - I click it but packets keep coming in. Also frequent spinning beachballs on my 1.5 GHz PowerBook G4 and it saves documents that don't open in Ethernal when double-clicked in the Finder and don't open when dragged onto Ethernal's icon - I have to go through the Open dialog. That's what I found in about 5 minutes of use. Needless to say, this would seem to need a ton of work.
