I've created a TitleWindow that gets popped up using
PopUpManager. When this gets added to the Application.application,
I can move this popup window around just fine (via mouse
click-n-dragging the top part of the window). However, when I want
to add this popup window as a child to a canvas (using addChild()),
I can see the window on the canvas but I can't move the window
around (seems to be static). I also can't close the window anymore
as well. Is there something wrong?
