I've only just started contributing to OpenStreetMap, so I may be doing something wrong, but I'm trying to add a note to a building and when I add the note to the 'note' box and then close the metadata editor, it doesn't seem to save. Furthermore, the Save button doesn't become enabled, suggesting that somehow the editor hasn't noticed that I have added a note. Does anyone know what's going on here?
