Program crashes when you put a crescendo hairpin on a Appoggiatura grace note.

I have replicated this problem several times now. In my situation, I need to attach a "p" dynamic marking to a 32nd Appoggiatura grace note. Then I attempt to attach it to a crescendo hairpin by clicking on the note and using the "h" key, and the program crashes immediately.

I can get around this by "attaching" the hairpin to a different note and simply placing it where I need on the page, but I thought I would inform you of this bug in case the programmers sought fit to fix it. Perhaps the grace notes have other attachment limitations as well?

Cheers,
