flash code causes url to open twice

The following flash code is a glow ball that is to go to a url when clicked.

This code when added (below) functions correctly but does launches the URL 2x. Please help.
btn_mc.onPress = function ()
{
   getURL("http://www.tomahawktko.com", "_self");
}

//import the flash filter classes that also included the GLOW filter
import flash.filters.*;
//import the tween classes to give a little bouncy effect to object 
import mx.transitions.Tween;
import mx.transitions.easing.*;
 //ok instead of putting those parameters directly into the GlowFilter Object
// I've assigned those parameters to variables for ease of change and understand
var glowColor:Number = 0xFFFF00;//color that will glow around the object
var glowAlpha:Number = 25;// transparancy of the color
var blurX:Number = 10; //initial value of color floodingin horizontal direction
var blurY:Number = 10; //initial value of color floodingin vertical direction
var glowStrength:Number = 3; // the more the value the more the strength of the glowcolor
var glowQuality:Number = 3; // qulaity of the glow, it is set to max now
var glowInner:Boolean = false; // unable inner glow 
var glowOuter:Boolean = false; // unable outer glow 
//all the Glow properties mentioned in the GlowFilter are assing to the variables
var glowMe:GlowFilter = new GlowFilter(glowColor, glowAlpha, blurX, blurY, glowStrength, glowQuality, glowInner, glowOuter);
// GlowFilter properties has given to the Object
btn_mc.filters = [glowMe];
//function for the RollOver event with dynamic Glow setting.Glow setting changes on RollOver
btn_mc.onRollOver = function() {
	growBall();
	this.onEnterFrame = function() {
		if (glowMe.blurX<40) {
			glowMe.blurX += 2;
			glowMe.blurY = glowMe.blurX;
		}		
		else {
			delete this.onEnterFrame;
		}
		this.filters = [glowMe];
	};
};
//function for the RollOut event that takes back the object glow to its initial stage
btn_mc.onRollOut = function() {
	shrinkBall();
	this.onEnterFrame = function() {
		this.filters = [glowMe];
		if (glowMe.blurX>10) {
			glowMe.blurX -= 2;
			glowMe.blurY = glowMe.blurX;
		} else {
			delete this.onEnterFrame;
		}
	};
};
btn_mc.onPress = function ()
{
   getURL("http://www.tomahawktko.com", "_self");
}
 
// button GROW and SHRINK code starts here
var xGrow:Tween;
var yGrow:Tween;
var xShrink:Tween;
var yShrink:Tween;
 
btn_mc._xscale = btn_mc._yscale = 50;
 
function growBall(){
    xShrink.stop();
    yShrink.stop();
    xGrow = new Tween(btn_mc, "_xscale", Elastic.easeOut, 50, 58, 2, true);
    yGrow = new Tween(btn_mc, "_yscale", Elastic.easeOut, 50, 58, 2, true);
	
}
function shrinkBall(){
    xGrow.stop();
    yGrow.stop();
    xShrink = new Tween(btn_mc, "_xscale", Elastic.easeOut, 58, 50, 3, true);
    yShrink = new Tween(btn_mc, "_yscale",Elastic.easeOut, 58, 50, 3, true);
}
 
 
 
/*

Well, one thing I would do is set my onPress handler to onRelease.  onPress is rarely used, as it can cause weird usability issues.

In your html file that you imported your swf in... let's say index.html you need to edit the code to set a parameter "allow script access" and set to always.

the script below is what automatically loads in dreamweaver when you import your swf, if you look towards the bottom you will see (<param name="allowScriptAccess" value="always" />) add this in manually into the html file and you actionscript code should work fine

<script type="text/javascript">
AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0','width','800','height','200','src','/flash/now_header','quality','high','pluginspage','http://www.macromedia.com/go/getflashplayer','wmode','transparent','allowscriptaccess','always','movie','/flash/now_header' ); //end AC code
