Browser button control

1

Flash MX, publishing for Flash 5: Is there a way to make the browser’s back button just take you to the home page? I hate when I get stuck in someone’s site like this, but I can’t think of a way to control this problem. The only thing I can think of is a “gate” page that is just html with a link to the main movie. That way, when a user forgets to utilize the lovely navigation I so painstakingly designed and coded, they’ll at least not be thrown out. Any other suggestions will be greatly appreciated!
