Hi kirupa people, I cannot use the PopUpManager class.

```auto
import mx.managers.PopUpManager
import mx.containers.Window
win = PopUpManager.createPopUp(_root, Window, true, {closeButton:true});
lo = new Object();
lo.click = function(){
    win.deletePopUp();
}
win.addEventListener("click", lo);

```

I copied this code from the flash help but I get

```auto
**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 3: Type mismatch.
     win = PopUpManager.createPopUp(_root, Window, true, {closeButton:true});
Total ActionScript Errors: 1 Reported Errors: 1

```

Note: I have window component in my library.

Any idea?
