Ok Perhaps I am doing something wrong but here is what is happening when I try to transpose one chord.

By the way I am a newbie.

1. Go to Notation window.
2. Chord is C
3. Click on OPT button
4. Transpose Semitone—Here I enter any number preceded by a – or + and it never does what I want it to. For instance, I enter the number 1 and click OK and it transposes from C to D. Then I type in +1 and it transposes to A#. What am I not getting here?
5. Also, when I go to Edit, Undo Transpose…nothing happens.
6. I thought maybe the problem was linked to what Key I was in from the start. Like if I forgot to set the key and then transposed , maybe that confused the program. But I started a new piece from scratch and am still finding the same problems.
I hope that clarifies things.

Thanks Jeff
