Immediate Open after Close with PopUpButton

Question

We are using a number of PopUpButton controls and are seeing some strange behavior.  When we try and close the button it immediately pops up 2 times and on the 3 starts to behave as expected.   This pop up button is on a View Stack and in a nested container.   I have not been able to figure out where the source of the open is coming from immediatly after the close.  I have done a lot of searching and have found some posts around ViewStacks and the popupbutton but nothing that sounds like what we are experiencing.
I know this is not a lot to go on, but thought I would give it a try.  Is there any tips that might be helpful in troubleshooting this issue?   Is there a way to figure out the source ("Where a event was dispatched")?   Any thoughts or troubleshooting tips would be helpful as my normal set of troubleshooting has not provided any clue to this point what might be causing this behavior.
Thanks in advance for any suggestions you might have.

Here is what is in the InitMenu
            public var printMenuItems:XMLList =
                <>
                    <menuitem id="menu1" label="Menu1" data="menu1" enable="true" />
                    <menuitem id="menu2" label="Menu2" data="menu2" enable="true" />
                    <menuitem id="menu2" label="Menu2" data="menu3" enable="true" />
                </>;
            private function initMenu():void
                printMenu = new Menu();
                printMenu.labelField = "@label";
                printMenu.dataProvider = printMenuItems;
                printPopUp.popUp = printMenu;
                printPopUp.addEventListener(DropdownEvent.OPEN, openHandler);
                printPopUp.addEventListener(DropdownEvent.CLOSE, closeHandler);
                printPopUp.addEventListener(MouseEvent.CLICK, clickHandler);
