MS.com cuts off score

It's one of those scores that is just on the cusp when it comes to the number of pages used as the layout is updated. Minor changes affect whether it takes up four pages or five. MuseScore re-paginates everything at the last moment as it interprets the score and adjusts the layout.

In the Title, reducing the number of spaces between RONDO and CAPRICCIO changes it from five pages to four but as soon as you finish doing this you go back to five again. Then when I go to Bar 39 and flip the direction of the tie on the G (top stave) it's back to four.In Bar 41 I flip the direction of the tie on the low D in the lower stave and it's back to five. After all that, if you select Bars 48 thru 53 and apply just a tiny bit of reduced stretch it goes back down to four and wants to stay there.

Very enjoyable piece, by the way.

When I download the score you attached to your post, it is 5 pages long - four full pages plus four bars on one system for page 5. However, the moment I do anything - even just a "select all" - it suddently shrinks down to four pages. This sort of layout shift was quite common in 1.3, but almost never happens in 2.0. The difference apparently starts at measure 10, which either fits on the second system or doesn't - as mentioned, the courtesy key signature is probably partially responsible for this. The method I described in my previous response is what you should do: add explicit line breaks using Add/Remove Line Breaks (using the option to add breaks to the end of each existing system), then reduce stretch by one notch. This is something I got in the habit of doing with all my scores in 1.3, because these shifts were quite common. I almost never see them any more, but your score proves it can still happen occasionally.
