On wxMac the scrollbars are not "built-in" like on the other platforms, 
so they are actual wxScrollBars and are considered children of the 
scrolled window.  So when you call DestroyChildren() it is nuking the 
scrollbars too.  So instead of using DestroyChildren you need to loop 
over the list returned by GetChildren and Destroy each child that is not 
a scrollbar.
