Up to now, I have been able to place notes at any point in time on the staff. Starting just this afternoon, the editor will only let me place notes immediately after notes that already exist. Also, previously, if I deleted a note, it just deleted that note without moving anything else. Now, it shifts all notes after it over to close the gap.
Is there some setting that I can change to put this back? I looked through the editor settings and did not find anything that seemed to match this situation.
