Full Browser Web Page

Seems like an easy task, but it is causing me all kinds of problems. I followed the instructions at http://www.kirupa.com/developer/mx2004/fullscreen.htm but can not seem to get a movie to take up the entire web page. I made a simple movie that is nothing but a blue box to test with. The link is www.sequiotavalley.com/test.html. In fire fox i can only see the bottom half of the box and in IE i can see the entire box but it does not take up the full page. Any ideas on how to fix this would be great.
