I never would have figured out its because of the textfield. Your proposed solution of an invisible item over the titlebar works perfectly, and since my real use case is a subclass of Panel I can easily integrate this approach. One odd thing maybe you can enlighten me on though is that it seems like I have to create the cover piece in updateDisplayList() because doing it in createChildren() doesn't work. The item isn't even visible if I create it in createChildren(). Any ideas why? Here is the code I have tried inside both methods. if(!c) { c = new Canvas(); c.x = c.y = 0; c.width = this.width; c.height = this.titleBar.height; c.setStyle("backgroundColor", 0x000000); this.rawChildren.addChild(c); } Thanks a ton, greatly appreciated.
