Score crashes regularly after transposing
Select a note and then select all.
Right click to change instrument from guitar to piano.
Hit OK or whatever to finish.
Note: This score crashes a lot since I transposed it from D to C (and a lot of other fussing around--I think it got corrupted?). I'm submitting just in case it helps reveal something. Oh, "Reported version" says 3.6 but I'm working in 4.0.
