(*) Double clicking to change the name of a track only works on startup. Once into a project, I can not rename a track.
(*) Key Editor only opens sometimes when clicking on a MIDI track. When it does open, the focus is rarely placed on the Key Editor Window. The Focus remains on the previous window. The Key Editor window does not move to the foreground, but stays in the background.
(*) Inside Key Editor at times hitting a note on the virtual keyboard will cause it to play 5 or 10 seconds instead of just the amount of time you hit the key. Restarting the application fixes this, until it happens again.
