Consider the following scenario.

• You are running Windows Vista on a portable computer.
• The portable computer is set to do nothing when the lid is closed.
• You connect a CRT monitor that uses a different screen resolution.
• You configure the desktop area to extend across the LCD screen and the CRT monitor. (This configuration is known as extended desktop mode.)
• You move a desktop icon to the right side of the LCD screen.
• You close the lid of the portable computer.

In this scenario, when you open the lid of the portable computer, the desktop icon changes location on the screen.
