Concerning instrument tracks in Arrange View - When I engage Mute from the FaderPort or from the Inspector for an instrument track the Mute button on the track itself becomes non-functional. It turns red when selected and grays out when deselected but does not affect the mute condition of the track (if Mute is selected on the FaderPort or in the Inspector). Furthermore, the Mute button on the track does not turn red when Mute is selected from the FaderPort or from the Inspector. This problem does not exist for audio tracks, just instrument tracks. There is obviously some kind of disconnect here. Please fix.
