The stacklayout attribute of GUIGroup does not compute the positions of child controls correctly when the visibilities of child controls are changed while the parent window remains unchanged.<br /> <br /> The usage of stacklayout for world weather is different than other uses (although other current implementations could be similar to the implementation of world weather). The problem is exposed now because world weather changes the visibility of buttons continuously based on user interactions (like cycling the world weather screens). The algorithm for collapsing buttons only works on the first pass (window load) -- if button visibilities change after the initial computation then you get the behavior we observe (the buttons migrate up the window on each subsequent pass where visibilities have changed again).
