I recently upgraded from 10.24 to 10.64. Now I can no longer lock my external audio track.
Before 10.24, the lock icons/buttons were always visible, next to the Mute and Solo buttons. Then in 10.24, there were only visible when hovering the mouse over their location. Though strange, still workable. Now in 10.64, they seem to be gone altogether. What's up?
I prefer to lock my audio track because I never want to change that when editing the video track.
