I use this technique with little issue (although I haven't tried it with
a wx.Notebook).  One thing you might try is to use an extra wx.Panel as
a container for the entire page.  So each page then would end up with a
single panel for the page, and each panel further containing *another*
single panel which contains your actual controls.  This way you can
simply destroy the second panel and recreate it and the layout is simple
enough that you shouldn't run into problems with sizers getting
confused.
