The MovieClip.getNextHighestDepth() method used in this example requires Flash Player

7 or later. If your SWF file includes a v2 component (version 2 of the Macromedia

Component Architecture), use the DepthManager class from the component framework

instead of the

MovieClip.getNextHighestDepth() method.
