this is the actal scenario in my flex application..
Do you know any best way to access the properties on the Application Object ??

for that i have tried the way...
- Component 4
<!-- PopupWindow.mxml -->
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
                xmlns:s="library://ns.adobe.com/flex/spark"
                xmlns:mx="library://ns.adobe.com/flex/mx">
     <s:layout>
          <s:VerticalLayout horizontalAlign="center" verticalAlign="middle"/>
     </s:layout>
     <s:BorderContainer id="bcPopupWindow" width="700" height="500" backgroundAlpha="0.8" borderAlpha="0.5"
                       borderVisible="true" cornerRadius="20" dropShadowVisible="true">
==     Some designing part   ==
     </s:BorderContainer>
</s:Group>
and for showing this
in Component 3 -
protected function btnShowPopup_clickHandler(event:MouseEvent):void
     myPopup= new PopupWindow();
     myPopup.width = this.parent.parent.parent.width;
     myPopup.height =this.parent.parent.parent.height;
     PopUpManager.addPopUp(myPopup,this,true);

hi
try changing this line:
PopUpManager.addPopUp(myPopup,this,true);  //adds popup to current object
to this:
PopUpManager.addPopUp(myPopup, root, true); //adds popup to top level object
it should fix the popup not centering properly - it is centering itself, but with respect to the current visual object (where your open popup code is). changing to root will add the popup to the top level and so centering it there will center it with respect to the application itself.
also, add this line below the one above:
trace(FlexGlobals.topLevelApplication.width);
and see what it traces out (in debug mode) - is it giving the correct value?
