XP (Pro) does not accept adding chords Ab,Bb,(Cb),Db,Eb,(Fb),Gb,
I'm using XP Pro and W10, Both with MuseScore 1.3 and 2.0.2
If using MuseScore 2.0.2. with XP and tryïng to add a chord symbol Ab....Gb by Ctrl K it does not accept the added b as second character Also no not a capital one: AB is not possible as well)
It will accept any other addition like # or whatever useful or not useful character you type but NOT the b. It is not a big problem for me because I just open some file which shows any available chord symbol with an added b and copy it into the file I'm editing. Then change the key in which I need and every next time I copy such chord symbol. Once available the whole chord can be editted to anything you like. But don't delete the "b", it just does not accept it. With 1.3 it is no problem. It is only a chord symbol problem.
