Bug description

Please see steps to reproduce.

Steps to reproduce

1. Create a score with a cover page (vertical frame + page break).
2. Set the "first page number" to 0 (page settings).
3. See how the pages are not laid out as expected (pages 1 and 2 should not face each other):

4. Save the file.
5. Close the file.
6. Reload the file.
7. See, how the layout is now correct:

The only error here is that this change should happen immediately (and not only be apparent once the score is reloaded).

[oMrSmith]

But wouldn't this mean, that achieving this layout is then impossible
as you can't descide on whether the first page appears left or right
independly from the numbering?

[oktophonie]

Yes, and that's how it should be.
If you want the first page with music on it to be a left-hand page, that page needs to have an even number.
If you need a single page before it for some reason, that page will therefore need to have an odd number.

[oMrSmith]

I get your point. I think it's an unnecessary limitation though.

It dosen't make sense to me, that MuseScore forbids pages with odd numbers
to appear on the left, if the user needs such layout.

The only reason, why pages with odd numbers always appear on the right side
in books, is because the book-cover dosen't get print on it from the inside.
But this limitation does not exist with printed sheetmusic.

So why not let the user descide?

Don't worry, this is my last comment on this ;)

[oktophonie]

It makes perfect sense and is how it's invariably done. A left-hand page is always even.
(This issue remains a bug, just not for exactly the reason originally thought)

(one nice example)
