Adding accidentals has changed in 3.3.3
Note: This is about note entry from the computer keyboard—not mouse entry.
Normally, in this mode of working, the only time you need to use the note-input toolbar is to add certain accidentals. However, the changes in 3.3.3 mean that accidentals are added from the toolbar in a different way to previous versions.
Create a treble staff score in C, say, then go into note-input mode.
In MS 2.3.2:
1. Add a B to the staff.
2. Now click a natural sign on the toolbar.
To do the same thing in MS 3.3.3:
1. Click the natural sign.
2. Add the B.
Alternatively in 3.3.3:
1. Add a B to the staff
2. Apply the accidental from the palette instead.
This is not the only difference: 2.3.2 allows you to return, in note input mode, to a previously added note and add an accidental from the toolbar "after the fact." However, 3.3.3 does not allow you to do this: you have to add the accidental from the palette instead. Or, alternatively step out of note-input mode and then add the accidental from the toolbar.
