title: python tkinter scrollbar and text widget issues
body: <p>I'm trying to get two text boxes that each have scrollbars. When I try this however:</p>
  
  <pre><code>from Tkinter import *
  
  root = Tk()
  
  s_start = Scrollbar(root)
  t_start = Text(root, width=50, height=10)
  
  t_start.focus_set()
  
  s_start.pack(side=RIGHT, fill=Y)
  t_start.pack(side=LEFT, fill=Y)
  
  s_start.config(command=t_start.yview)
  t_start.config(yscrollcommand=s_start.set)
  
  s_end = Scrollbar(root)
  t_end = Text(root, width=50, height=10)
  
  t_end.focus_set()
  
  s_end.pack(side=RIGHT, fill=Y)
  t_end.pack(side=LEFT, fill=Y)
  
  s_end.config(command=t_end.yview)
  t_end.config(yscrollcommand=s_end.set)
  
  root.mainloop()
  </code></pre>
  
  <p>This happens:</p>

  <p>In case this isn't clear, those are two separate text boxes, with the right textbox functionally bound to the inner scroll bar, and the left textbox functionally bound to the outer scrollbar.</p>
