I pressed some keys and suddenly on the right side of my screen, where in general is a pane with pepples to switch between Object manager and Object properties (or other selectable windows) an additional pane also with the Object properties is to the left. If I try to deactivate the window (Windows / docking windows) and deactivate the Object properties, it vanishes in the right side, but the left pane still remains. How to remove it?
I have the German Version, might be, that I did not translate all names correct - please apologize
