+    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.
