How to rescue an off-screen window

On Windows, it is possible to get into a situation where one or more application windows are positioned entirely outside of the bounds of the viewable area of the monitor. This can sometimes happen with a machine in a multi-monitor setup where one of the monitors is disconnected; an application window that is in the minimized state at the time that a monitor is unplugged can, when the window is restored (un-minimized), be restored to a position somewhere off the screen, in what was the viewable area of the disconnected monitor.

Here's one way to "rescue" such an off-screen window and bring it back onto the active monitor:

1. Make the off-screen window the active window by clicking on its icon in the Windows Taskbar.
2. Press Alt+Space, and then press the M key. This will activate the window's system menu, and put the window into "move mode."
3. Press any arrow key once. This will put Windows into a mode where moving your mouse will drag the active window around the desktop (even without holding in a mouse button).
4. Move the mouse around until the window reappears on the active monitor.
5. Left-click once with the mouse (anywhere) to exit "move mode."

That's it! This works on Windows XP, Windows Vista, and Windows 7. I hope this helps!
