You must see two "perforated" vertical lines close to the start button (use to resize the Quick launch area.) If you don't make out them, your bar is most likely locked. Move the pointer over the rightmost vertical line as well as the pointer changes to the stretch symbol <-->. HOLD DOWN the left mouse button and drag that bar far to the right so the quick launch area is massive. Resize the bar vertically; drag the perforation back to where you desire it.
