Dear Sirs,

I'd submit you this "music theory bug" that it is not allowed (at all I'd add!) in such great program as BIAB, especially if it is used to teach as well (as in my case) or to print sheets to read for playing.

So shortly, if I'm entering chords in C#min key (= 4 sharps in the key) and I type G#7 and I need the third on bass (B#), IT IS NOT POSSIBLE AT ALL that (1) BB does not allow me to enter neither B#, so I need to enter C (!!) and the result chord is G#7/C (!?!), a total "music theory disaster" and not educational huge mistake!!

CORRECT NOTATION MUST BE G#7/B#, simply, of course.

Please, you are really invited to fix this "music theory bug" in BB. Thanks.

Best regards.
