Hi.
PopUpManager.removePopUp(someWindow) really doesn't destroy someWindow.
If you create someWindow in some function it should be destroyed by garbage
collector.
Otherwise... well sometimes I simply use one object for every pop-up of
special type, e.g.
private static var _popUp : IFlexDisplayOb
I am seeing behavior where pop ups seem to just be getting hidden by
removePopUp(), resulting in a growing stack of them each time a new
one is added. I create the pop up like this:
var p:IFlexDisplayObject = new FailurePopUp("Error msg");
PopUpManager.addPopUp(p, model.mainAppCanvas, true);
PopUp
