wxScrolledPanel in a Notebook - background problem

I just upgraded to

- Python 2.3
- wxPython 2.3.4.1

I am on Windows XP Professional.

The problem is that the notebook page based on wxScrolledPanel has the "old" look (non XP controls).

Couldn't find any solution, except a mail by Julian Smart with a work around suggestion to colour the controls after adding page to the notebook, so I do a SetBackgroundColor(GetBackgroundColour(fromanotherpanel)) for the wxScrolledPanel and all its child controls.

By the way the problem does NOT happen on notebook pages based on wxPanel and I use standard colouring throughout my application.

Besides this problem, all is working very nicely, a big thanks to everyone involved in putting it all together.

Best regards
Werner
