If "Always show notes" is active, there is no context-menu in the area where the note text is displayed (just below the node's body text).

Add some node
Add a note to this note.
Select View -> Notes -> Always show notes. (This will make the note text to be displayed just below the node's body text.)
Right-click on the note text -> Nothing happens.
I'd expect to get a contect-menu here.
In contrast, the context-menu is functioning on "note details".
I should have written, that I'*m expecting to get the node's context-menu.
Please note: If the note text is smaller than the body text, there is a special effect: When you right-click on the node text, you will get *no* context-menu, but when you right-click right of the note text, you'll get the *maps* context-menu. (The technical reson for this effect is easy to understand. I just documented it here to describe the problem more precice.
