I was clicking around in the settings and I did something wrong and lost the cube spinning 3D effect when clicking with the mouse pad on each desktop. The Keyboard shortcuts still work fine (ctrl+alt+ arrow). Any idea on how to get that effect back?
1. Are you sure clicking on a desktop you are really moved to another desktop?
2. Does Ctrl+Alt+(Left_mouse_button_pressed)+(mouse_moving) rotates the cube?
