Moving grace notes on score with linked staff causes crash
1 Create guitar score with a pair of linked staves
2 Change one of the staves types to tablature
3 Insert crotchet
4 Drag grace note from palette to crotchet
5 Select grace note and press up or down arrow to move
If you save the file, close and re-open it the crash does not occur. Saving without closing it is not enough to prevent the crash.
This happens every time without fail but as it is happening as I work on a score rather than specific testing I am not sure whether all of the steps above are necessary to cause the crash (I will do some more testing when I have time over the next couple of days and update the information).
