To be honest, it doesn't really surprise me that you cannot copy Tkinter objects. If you could make a copy of an object which is displayed on the screen I would expect that copying would create another object on the screen, and that probably isn't what you want. Other uncopyable objects include files, stack frames and so on. The deepcopy protocol does allow you to specify how complicated objects should be copied. Try defining __deepcopy__() in your objects to just copy the reference to the Canvas object instead of the object itself. -- http://mail.python.org/mailman/listinfo/python-list
