If I am editing a master page, and I save (either Cmd-S or using the menu option), I’m summarily dumped out of the master page editor, back to the music of my score. This is unideal, to say the least. Saving the file really shouldn’t make my view change.
(I am a compulsive file saver — I admit it. Dorico crashes less than it used to, but not infrequently.)
