I would strongly recommend not calling your class the same
as the standard widget. I don't think thats causing
issues here but I wouldn't be surprised! Its a bit like overrriding
built-in Python functions. Users of wxPython expect "ScrolledWindow"
to refer to the standard one...

Being picky, you attached an RTF file which mostly won't
cause a problem, but you might as well just have attached
the original python code since it truly is a text file! And that
way there is no chance of anything getting clipped or
distorted during the cut n paste or import/conversion process

Your code looks like:

class ScrolledWindow(wx.ScrolledWindow):

    def __init__(self, parent, id, style = wx.LC_REPORT):

        wx.ScrolledWindow.__init__(self)



Notice that you do not pass the parent etc onto the superclass 
constructor.

You need something like:



        wx.ScrolledWindow.__init__(self, parent, id, style)



HTH,
