I tried to assign a new key(lctrl+lshift instead of lctrl+F5) for run-
mode in option in v.2.5.2. I tried the new key and it didn't work. And 
then I got lots of messages.
So I killed the IDLE and the rest of python. And run IDLE again, 
background process indicates some activity for 5secs. And then it was 
gone. No IDLE window showed up. 
So I uninstalled the 2.5.2. and installed the v.3.1.1. The installation 
process went ok, but when I starts IDLE. Nothing happens.
I tried and run idle.py in cmd, while I'm a vista user and got this:

What do I do to get this up and running?
