Chord spelling with flat symbols

Using MuseScore Pre-release r1354 for Windows on Windows XP Pro.

I there a way to cause chord symbols that contain flats to be shown with a flat symbol instead of a lowercase 'b'. If I enter the chord b-flat major seventh, it is spelled Bbmaj7 (with the 7 superscripted). It would be more legible if the flat sign were the same as used in the flatting of notes instead of a lower case 'b'.

Does this have something to do with how I am entering chord names? Is there an option that I can set so that chord names use the proper symbols? Missing font? Bug? Not sure ....

Thanks,

EulerOperator
