Hi. I have got a slight problem to set the location of the Source and Messages panes in the Lyx UI (Debian, LyX Version 2.1.3). For some reason, my Lyx UI has been reset, so the Source and Messages panes were not displayed. After having them displayed again (View / Source Pane and View / Messages Pane), I cannot find a way to display them side by side: they are either undocked and hence on top of the main pane, or displayed as two tabs - I cannot have them shown simultaneously side by side.
Am I missing something ? Thanks, Gilles
