Shooting my own troubles... my first post was spectacularly wrong (I'm beiju). I said that there was a delay... well, that is not true. It just took me thirty seconds to two minutes of clicking to hit the gray part, which is the only part that will open the application. It does run pretty well under tiger, except for that it doesn't communicate well with other applications' windows... it usually opens under the active application and you have to click the window to bring it to the front. Still, that's no reason to not use a great app, although i'd still like the 3.6 version if anyone's still got it.
