I don't know how ;( but somehow I managed to change the layout for the
GUI. Now I have the Result-panel in top of the Info-panel.
How can I restore the original lay-out (Result to bottom-left and Info
to bottom-right)?
You can hover your mouse over the barred line at the top of each window to move it. (e.g. in the hastily-made screen grab attached, the lines inside the red box)
