#7 in minor.

When the root of a chord is the raised seventh degree of a minor key, and it is a “black key” it should always be displayed as a sharp, not a flat.

This currently works correctly in BiaB in some circumstances, but not in others. Where it works:
- When it is the third of a V chord, such as D7/F# in the key of G minor.
- On i chords with a major seventh in the bass (with one exception), such as A/G#
- In concert key notation it also works most of the time for diminished seventh chords such as G#dim in the key of A minor (also with one exception).

Here are the circumstances where the raised seventh of a minor key is not displayed correctly:
- When transposing to the key of G minor the F# roots are incorrectly displayed as Gb, as in Gbdim and Gmin/Gb. These should be F#dim and Gmin/F#.
- When transposing the notation for non-concert pitch instruments, the roots of diminished seventh chords are incorrectly displayed as flats -- Dbdim, Ebdim, Gbdim, Abdim, Bbdim – they should be C#dim, D#dim, F#dim, G#dim, A#dim.
