I’m making a menu to navigate around my site and I can’t get the buttons to open up links in the same window. It only opens in a pop up window. Here is my code, plz tell me what I need to do.

 
home_btn.addEventListener(MouseEvent.CLICK,buttonClickHandler);
function buttonClickHandler (event:MouseEvent):void {
 navigateToURL(new URLRequest("[http://brittonbethel.com](http://brittonbethel.com/)"));
 trace("I'm Clicked");
}
