Every once in a while you may find that a window or application is off screen and can't be dragged using the mouse cursor. The window may just be visible on the edge of your screen, but just can not be grabbed or moved using your mouse. Sometimes this can happen while using only one monitor with extended desktop turned on. Applications typically will remember the position that they were last in when you closed down the app, and will return to that spot when it is opened back up. To get around this problem here are some steps to move a window that is off screen using the arrow keys on your keyboard.
Using only keyboard shortcuts:
1. Hold down Alt + Spacebar.
2. Press the M key on your keyboard.
3. Use the arrow keys to relocate the window.
4. Press the Enter key when you have positioned the window in its desired location.
Using your keyboard and mouse:
1. Right click on the program you want to move in you Windows Taskbar.
2. Select Move (you should then see a cursor with four arrows).
3. Use the arrow keys on your keyboard to move the window in the direction you want.
4. Click on the title bar when you have the window in its desired location.
