Seeing this comment reminded me of some conversations I've seen in 
comp.lang.python recently.  Apparently newer versions of IDLE create a 
subprocess to run user-code in (so that IDLE runs in a different 
interpreter than the code you type into IDLE), and communicates with 
that subprocess through sockets on the loopback interface (that is, 
the 'network connection' that connects only to itself).  Overly 
aggressive firewall programs may block those socket operations.

I'd check whether XP's built-in firewall is enabled, and if so, check 
whether it might be blocking connections to loopback / localhost / 
127.0.0.1 (all of these indicate the same thing).
