Great that I helped. No need to delve into SDK source. I found the bug: https://issues.apache.org/jira/browse/FLEX-16946
Some notes: More performant way to move popups is popupitem.move(x,y) To get background FlexSprite, I used: bgsprite = systemManager.getChildAt(popupsitemIndex - 1) then checked: if bgsprite.name = "modelWindow" then you use bgsprite.graphics to redraw it: - clear() - beginFill(..use your default Alert CSS style values...) - drawRect(0,0,win.width, win.height) to stretch it fullscreen -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Modal-background-is-not-centered-if-modal-is-shown-while-minimized-tp15286p15292.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
