Missing+Desktop+Window

Sometimes when you open an application, the relevant window does not appear on your screen, even though an icon for the app is shown in the taskbar at the bottom of the screen. This happens if you have Windows 7 set up to use two displays and one of them is turned off, or you have a laptop that has recently been plugged into a projector. Windows 7 is trying to display the window on the non-existent display.
 * Missing Desktop Window **

To display on the correct screen :-
 * 1) Click on the window's icon in the taskbar.
 * 2) Press [**Alt**] + [**Space**] then press [**M**].
 * 3) Hold down the right arrow keys to move the window onto your main monitor. If the window does not appear after a few seconds, hold down the left arrow key instead.
