call self.text.update_idletasks() or self.text.update() after you've modified
the contents, but before you enter the test loop.  it's probably easiest to
add it to the addMessage method:

  def addMessage(self,message):
    self.text.insert(END, '\n')
    self.text.update_idletasks() # <-- force update
