[flexcoders] systemManager & PopUpManager & Alert windows

[male_designer]

I recently needed to be able to close all popup windows at once, so I
began implementing the "PopUpManagerChildList.POPUP" technique to
catalog these windows using systemManager: 

PopUpManager.createPopUp(this, UserDetailsWin, true,
PopUpManagerChildList.POPUP));


Problem is - all my Alert windows show up beneath the popups created
as above.

Does anyone know how to fix this?
