Mx.core.Window open() not working on PC / Windows XP

Question

This seems odd to me almost like some sort of popup blocking trouble...which wouldnt make sense in AIR.
I have an app the trys to create a mx.core.Window in the windowComplete event. It works fine on my mac and on linux, but on the pc I have for testing it refuses to open the window. I have  verified that the windowComplete event is firing and calling the appropriate function. If I call the same code from a click handler of a button in the main WindowedApplication he window opens fine.
Am I missing something? Is there something special I have to do for the pc?
Thanks in advance.

Sure, thanks for responding:
<mx:WindowedApplication windowComplete="init()" .........removed excess here
     <mx:Script>
          <![CDATA[
               import mx.core.Window;
               protected var theWIndow:Window;
               protected function init():void{
                    theWindow = new Window();
                    theWindow.open();
          ]]>
     </mx:Script>
</mx:WindowedApplication>
In my actual code I have a mxm component that extends Window, so the Window type would be that instead, but since it directly extends it there is no difference. I am actually using the fb.FBConnect code from the facebook-actionscript-api and its open() call also fails on the pc...that is unless I start the process from a flex Button click, then it all works.
