I'm trying to get the link to open in the same window instead of a new window, it's currently set to _blank. I tried _top, _self, _parent. When it's set to anything other than _blank the link doesn't work.

Code:
import flash.display.*;
import flash.events.*;
hyperlinkbutton3.addEventListener(MouseEvent.CLICK, hyperclick3);
function hyperclick3(event:MouseEvent):void {
    var url:String = "http://google.com";
var request:URLRequest = new URLRequest(url);
try {
  navigateToURL(request, '_blank'); // second argument is target
} catch (e:Error) {
  trace("Error occurred!");
