Thanks Chris. When I try the following (to see the types of the classes involved): #!/usr/bin/env python import wx from Debug import _line as line class CopyAndPaste(object): def __init__(self, *args, **kwargs): super(CopyAndPaste, self).__init__(*args, **kwargs) print line()+". type(wx.Frame):",type(wx.Frame) print line()+". type(object):",type(object) I get: $ python -u CopyAndPaste.py 9. type(wx.Frame): <type 'type'> 10. type(object): <type 'type'> And I don't understand what it means... In any case, it does not seem to help me resolve the metaclasses exception.
