解决Python IDLE启动失败的问题

Python3.1 是3月份刚release的,装在vista上后,报如下错误信息:

IDLE's subprocess didn't make connection.Either IDLE can;t start a subprocess or personal firewall software is blocking the connection

临时解决方式:
在目录C:\Python31\Lib\idlelib下,找到PyShell.py
找到下面这行:
use_subprocess = True
改为:
use_subprocess = False

然后删除同一个目录下的PyShell.py的compile文件.
重新启动后,IDLE顺利打开,但是No SubProcess.
