 When wx.ListCtrl is used with listmix.ColumnSorterMixin, the intial
 alignment of the list headers is incorrect on Windows. (It is fine on
 Solaris and Mac.) After a column has been sorted by user by clicking on
 it, the header alignment becomes correct. This can be seen in wxPython's
 ListCtrl demo also.

 The workaround to this seems to be to duplicate what sorting does to
 column headers i.e. reset/change the column image. So the following
 example works

 {{{
 class FooList(wx.ListCtrl, listmix.ColumnSorterMixin ...):
     def __init__(...):
         ...
         ...
         wx.CallAfter(self.workaround)


     def workaround(self):
         for n in xrange(self.GetColumnCount()):
             self.ClearColumnImage(n)

 }}}
