I'm finding that the "Conflicting Changes" notepad (one of them, at least) is not disappearing and can't be deleted. It's ugly seeing it there in the interface, when there's nothing I can do about it. Deletion is impossible, as the trash can and delete menu options are disabled when that notebook is selected. The conflict was resolved back in November, and it contains 0 notes, but remains sitting there like an ugly mess. How can I permanently delete it?
