When using the Score Editor and with the auto scroll on, each time a page turns, the active staff changes to the last staff .
This is really boring if you have a project with lots of tracks (like an orchestral one) and you want to follow the Flutes track and each time the page turns it goes to the last track of the score (Basses).
