Have you ever had the problem where you inadvertently moved a window outside the boundaries of the screen? Or your display was stuck in a very low resolution because the Display Settings dialog box was bigger than the screen at that resolution?
There's an easy way to move a window without using the mouse; by using the keyboard arrow keys.
Right-click on the problem window's icon in the taskbar and, in the popup menu that appears, select Move. Then use the keyboard arrow keys to move the window to a position where you regain control of it.
