You are now meant to use modals using addChild, but when adding the window as a popup, see:
modal:Boolean (default =
true, the window is modal which means that the user will not be able to interact with other popups until the window is removed.
Thanks very much for your reply.
But I can not use because the addChild PopUpManager.addPopUp performs an effect ...
I didn't quite understand that Gilberto
What performs an effect?
Or do you need a effect performed?
