I'd rather try to avoid using absolute screen positions in the UIManager. If we must, then UIManager should have a method to access the screen dimensions. But it would be better to hand in a reference to the UI object (window, widget, etc) and the dialog would automatically be placed on top of that object, or centered otherwise.
