I've setup a testcase with an external panel. When I click the menu-bar icon (top left) the external panel is sliding in 2 pieces ("close" and "page A") items, and the rest "page b,c,d".  Same splitted sliding effect is occuring when the panel is closing.  First the bottom 3 items dissapear, then the top 2 items.

This behaviour is not quite pretty.  Bug in 1.4.2?
