Playback doesn't move score

This topic has probably been covered by previous discussions but I have been out of action for the last year or so.
Since I upgraded Musescore the playback function no longer moves my score pages to let me follow the music on screen. Is this a deliberate modification or not made a setting?
Most annoying as I quite often play or practice directly off the screen.
Could someone point me in the right direction.
Thanks
Peter
