External protocol request (pop up)

1

Greetings

I am messing around with launching applications from within flash,
all this works great, yet 1 thing i can’t resolve

i get a pop up that says “external protocol request” in firefox/explorer/etc when i run it online
i have to click it and then the code continues, is there a way to prevent this?

the Security.allowDomain(); isn’t what i look for
tried to read upon Security.APPLICATION(); but it leaves me where i am right now

edit:
here is what code i have relevant to what i aught to do, i blanked out variables for obvious reasons.
<code>
function DOIT ():void
{
trace (“doing it”);
var TODO:String = //my action
//var requ:URLRequest = new URLRequest(TODO);
//navigateToURL (requ);
}
mc.addEventListener (MouseEvent.CLICK,DOIT);
</code>

apparently it only works with the urlrequest//navigateToUrl

any tips where to look for?
Thanks
