This is a layer script that runs with Navigator 4.0 or better only. You'll notice the author has made it so the item makes nice clean stops, like on ice.
Please note: This script is being offered in simple text format. When you click to Grab the Script, the text should display. Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
