It's possible that the PAGE_CHANGED event is not being sent to the 
notebooks themselves, only to the parent.  (Although that should 
probably be considered a bug.)  Try this instead:


       self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.OnPageChanged1, 
self.nb1)
       self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.OnPageChanged2, 
self.nb2)
