I think you could add something like this to DnDHandler.__init__() :

        def _return_break(widget, event):
            return 'break'
        self._id = widget.bind('<B1-Motion>')
        widget.bind('<B1-Motion>', _return_break)

which should remove the motion-selection binding and then restore it after
the dnd operation has finished by adding

        self.initial_widget.bind('<B1-Motion>', self._id)

to the end of DnDHandler.finish() (untested however).

Regards

Michael
