Howdy Doug,
Thanks for posting the file - that's always helpful!
The Staff/Show Instrument Transposed Pitches was "on" for this file. Since the staff is transposed to a G instrument (use Staff/Transpose Instrument Key to check and/or change if necessary) then the Cmin in concert pitch was showing as Fmin in the transposed staff.
To show concert pitch (Cmin), you can use Staff/Show Concert Pitch.
(I always find it easier to do my composing in concert pitch, and then transpose the notation for other players. But that's probably because I don't play any transposing instruments
)
ttfn,
Sherry
