Resizing a window in two directions at once

• Move the mouse pointer to one of the corner edges of the Welcome Center window.  You will see that the mouse pointer changes shape to become a diagonal line with an arrow on each end. Press down the left hand mouse button and while keeping it pressed, move the mouse pointer up or down and left or right. When you release the mouse button the window will be resized both vertically and horizontally, depending on which direction you move the mouse pointer.  Experiment with resizing the window.
  
  Also experiment using the other corners of the window to resize the window.
  

• Before continuing try and resize the Welcome Center window to its approximate original size and position.  You should be able to see other items on the screen behind the window.
