Note still played after having been deleted.
0) Open the score attached.
1) Press space (or your custom shortcut) to start playing from the beginning.
2) Stop playback (it makes no difference how long you've left it playing).
3) Select with the mouse, say, the third note, and delete it.
4) Press the shortcut to "select previous measure" in order to have the first note selected.
5) Press space again.
The note you just deleted is still played.
There's lots of odd things about this bug: it won't happen if you haven't played the measure right before deleting the note; it will only happen the first time you play the measure after having deleted the note (if you stop playback and repeat steps 4 and 5, the deleted note isn't played a second time); it also won't happen if, in step 4, you select the first note of the measure with the mouse instead of using the keyboard shortcut...
