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.
This behavior occurs because of the difference in the aspect ratio between the primary monitor and the secondary monitor. This behavior is by design in Windows Vista.
