title: Python IDLE is not starting on Windows 7
body: <p>I used to use Python 2.7 and then IDLE was working. I uninstalled it and installed Python 3.1.<br>
  Right now Idle cannot launch. What should i do to get it running?</p>
  
  <p>NOTE:
  I tried c:\Python31\pythonw.exe c:\Python31\Lib\idlelib\idle.py<br>
  i uninstalled 3.1 and installed back 2.7, not working neither...</p>
