 Even when the title bar or sizing frame is off-screen and not reachable by the mouse cursor, you can still move or resize a window. 

1. Click on the visible part of the window and press Alt-Spacebar to bring up its system menu. 
2. Then press S (for Size), press the right arrow key(->) to select the right-hand edge of the window, and press the left arrow key(<-) repeatedly. 
3. When the window is reduced to a manageable size, press Enter.  

                                             (or)

1. To move a window whose title bar is not visible, click the window or its corresponding taskbar button and again press Alt-Spacebar.
2.  Even if the window is entirely off-screen, not visible at all, the system menu will appear as close to it as possible, so you can use the menu's location as a pointer to the "lost" window.
3.  This time press M (for Move), use the arrow keys to bring the window back into view, and press Enter when you have it back under control.

Enjoy....
