Mitch,

Move your mouse OVER the Start button and right click. A short cut menu should appear. Click on "Properties" then select the Taskbar tab. Make sure that the "Lock the Taskbar" selection is NOT checked. Then, click and HOLD the left mouse button somewhere in the toolbar area and drag the toolbar down to the bottom of the screen.

Sorry if this sounds a touch condescending. I don't mean it to be, but I'm not sure of your computer abilities.

Hope this helps.
