Sure would make a nice exercise checking this one out on your own . . .
No reason to assume I had not.
In fact I already had, hence the question. (In my case, you can count on that.)
Simply changing to the Jazz Chord Symbols font did not give me your top (readable) display, unfortunately.
Extra details on
exactly what you changed and where are welcome if you care to provide them.
An alternative would be to post a file from 'Save scheme' in the display options dialog. It should be impossible for me to load your scheme and not see what you see. (At least that's the theory!)
