Hi Marc, many thanks, that cracked it. The right pane was "missing", in that it had moved so far over that I couldn't see that it should exist (and had obviously forgotten it should be there!) There is actually a grey bar a couple of pixels wide, but it gets lost in the window shadow. This is on Gnome 3.28.2. I guess as far as Pasaffe is concerned, this is user error.
