Two bugs

1. when NOT in Note Input Mode, although the duration of a note can be changed by clicking on a note and then clicking on one of the note durations int he toolbar, the same cannot be done with the Q and W keyboard shortcuts, although these work fine when in Note Input Mode

2. I noticed that MS reliably crashes when undoing a Beam Properties operation (double click on "Start beam" with two notes selected, then Undo)

I hope this helps!
