     There is an old (and apparently unsolvable) bug when placing a
-    window with a nonstandard background colour in a wxNotebook, as
-    the notbooks's background colour would always be used when the
-    window is refreshed.  The solution is to place a panel in the
-    notbook and the coloured window o nthe panel, sized to cover the
-    panel.  This simple class does that for you, just put an instance
-    of this in the notebook and make your regular window a child of
-    this one and it will handle the resize for you.
