title: Python Turtle Graphics Window only Opens Briefly then Closes
body: <p>I have recently begun using the turtle module in Python, and I admit, I am a complete novice. I have been having trouble getting the graphics window in which the turtle does its drawing to stay open. Even when I try to run something as simple as this:</p>
  
  <pre><code>import turtle
  wn = turtle.Screen()
  tur = turtle.Turtle()
  tur.forward(50)
  </code></pre>
  
  <p>all I get is the Python launcher icon to appear on my dock for a split second and close. Any help is appreciated, and I am, by the way, doing this in Aptana Studio 3. </p>
