It's not the problem with the program. It's a problem with IDLE. You've 
got a software firewall or some other programs blocking IDLE to make 
connection with the python subprocess:

The workarounds are either (from best to worst):
- create a rule to allow python to connect to localhost in your firewall
- don't start more than one instance of IDLE, it could messes things up 
sometimes
- restart your machine, it might be some previous IDLE stuck and messing 
things up
- start your program from the command line (without IDLE)
- start IDLE without subprocess, be warned that this means your program 
runs in the same python instance as IDLE itself and if your program 
pokes around too much it will messes IDLE up. Run this in command line 
or make a shortcut: C:\Python26\python.exe -m idlelib.idle -n (adjust 
path and version appropriately)
