Finale 2011b

Windows 10

I've written a number of arrangements using Finale, and frequently use Playback to see how they sound, find errors etc. It's usually worked well, with a small bar moving from note to note to show what chords are being played, and the score jumping from page to page as the bar moves off the page.

But at some point some months ago, I must have pushed a wrong button or three. It still plays back, and sounds fine as expected, but now there is no moving bar. And the score starts off at the beginning just as it used to, but when the part being played moves off the page, the pages don't move, and I can't see the notes being played for the later parts of the piece, on the screen.

Anyone have any idea what dumb thing I might have accidentally done, to stop it from scrolling as it plays back?
