Hairpins malpositioned, causes crash upon repositioning
When you select a note, then select a hairpin from the Master Palette, a hairpin appears above the staff. Single click and hold in order to move it around shows that the hairpin belongs to the staff where your note is at. Double clicking it reveals that it belongs to the staff above. Trying to reposition the hairpin causes the staves to re-space themselves as you see in the diagrams, and on one occasion, a crash.
