FULL SCREEN MODE, the pages don't jump to the left after a while.

When I 'play along' with a long score, about half way through playback, the 'full screen' pages stop moving to the left. The page on the righthand side of the screen will sit there and not move to the left until the playback gets to the end of that page. Once it moves to the left, the next page is then only partly showing. The first third of the page has disappeared. The score keeps playing in this fashion until the end.

It is very frustrating when you do not know what the next few notes will be. Shorter pieces play with no problem it is just the longer scores that do this.

I am using windows 10 (on my desktop).

I have attached a word document showing a 'print screen' drop of how the full screen looks when I'm playing. hope it makes sense.
