Right-clicking the frame cursor next to a selection shows menu items for both
The frame selection gives items like Cut/Copy/Delete, the frame cursor gives Paste/Insert. You should either see one or the other, but if you right-click a frame cursor while you have a frame selection, it combines the options from both, which is incorrect. If you right-click on the cursor, it should deselect, and then only show the options from the frame cursor.
