When you call removePopUp(), you're removing the pop-up from the display list. There's no direct memory management in Flash/Flex. Assuming there are no other references to that window, though, the window should be garbage collected. Now that's the thing -- looks like there's some reference to it somewhere. Here's a simple example without any event listeners. <?xml version="1.0"?> <mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml"; xmlns="*" width="400" height="300" title="Window"> <mx:SWFLoader source="AYB3.swf" width="100%" height="100%" /> </mx:TitleWindow> And the window is popped-up here. > <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; xmlns="*"> <mx:Button label="Launch Window" click="launchWindow()" /> <mx:Button label="Remove Window" click="removeWindow()" /> <mx:Script> import mx.core.*; import mx.managers.*; private var window:IFlexDisplayObject; private function launchWindow():void { window = new MyWindow(); PopUpManager.addPopUp(window, this); PopUpManager.centerPopUp(window); } private function removeWindow():void { PopUpManager.removePopUp(window); window = null; } </mx:Script> </mx:Application> I'm setting window to null. In theory it should be garbage collected and the .swf content in the window should stop playing (no sound should be heard). This doesn't happen.
