Description

Steps to reproduce:
1. Create an app with a PopUpMenuButton component that calls an event handler function upon itemClick.
2. Call Alert.show() in the event handler function (see attached demo app).
3. At runtime, select item from PopUpMenuButton's drop-down list.

Actual Results:
The Alert window appears in the application upper left corner.

Expected Results:
The Alert window should be centered on the screen.

Workaround (if any):
(a) Explicitly position the Alert with:
private function itemClickHandler(event:MenuEvent):void

{ var theAlert:Alert = Alert.show("Menu label: " + event.item.@label, "Menu value: " + event.item.@value); theAlert.x = (width/2) - (theAlert.width/2); theAlert.y = (height/2) - (theAlert.height/2); }

(b) instead of explicitly setting the x/y and doing "math", use the PopUpManager class's centerPopUp() method:
var alrt:Alert = Alert.show("any old label");
PopUpManager.centerPopUp(alrt);

(c) display the Alert using callLater().

Appears to be a regression from between 3.1 and 3.2.
