How to Resize
To make a window fill the entire screen, click its Maximize button or double-click the window's title bar.
To return a maximized window to its former size, click its Restore button (this appears in place of the Maximize button). Or, double-click the window's title bar.
To re-size a window (make it smaller or bigger), point to any of the window's borders or corners. When the mouse pointer changes to a two-headed arrow (see picture above), drag the border or corner to shrink or enlarge the window.
