clicking footer text corrupts parts
In a score with footer text and parts, clicking the footer text while viewing a part turns the part into a full score. Opening a different part tab in the project seems to revert the part back.
1) create a score
2) add footer text (or add Copyright text in New Score Wizard in step 1)
3) go to Parts and make parts
4) go to one of the part tabs
5) click the footer text
Result: the part becomes identical to the the full score until you open a different part tab.
Additionally, MuseScore will crash if you try to close the project while viewing the corrupted part.
