trailing measure is not a measure?
I just installed 3.2.3 on Windows 10 and opened an old score that I had never quite finished from a long time ago (a much older version of Musescore). It complained about the final measure.
When I go to have a look, I see three of the four staves are correct and the fourth is just empty. The problem is, I cannot do anything with this measure. I cannot insert a note, I cannot delete it, I cannot select it at all, I cannot select it as part of a range of measures, etc. It seems to be there but not really a measure.
Also, somewhat related (simple) question: I have been searching the docs for how to split a measure but only for one of the staves. I know this must be easy, but I cannot find it. When I try to split the penultimate measure on the bad staff, it splits all four staves at that measure. How do I operate on only one of the staves?
