title: Can´t get Focus on Python Tkinter Window
body: <p>I am Programing a small Program in Tkinter and wanted to have two windows open. Then i wanted to bring one Window in front. Program Code:</p>
  
  <pre><code>from tkinter import *
  
  root = Tk()
  root.title("ROOT")
  
  new = Tk()
  new.title("NEW")
  new.lift()
  
  root.mainloop()
  new.lift()
  
  new.mainloop()
  
  new.lift()
  </code></pre>
  
  <p>What did i did wrong with new.lift? New dosn´t come to front :(
  Does someone know how to bring a Window in front and give the Window focus?</p>
