I bet someone already asked this but I can't find the thread. I am using windows XP home edition. I loaded python 2.6.6 off the web as it is the same version some of my code is written in. When I click on the idle GUI I get no response. Tried setup reload/repair to no avail. Any suggestions?

Hm, it could be a firewall issue. Normally, idle uses the port 8833. You may have to open this port on your firewall.

You may need to add the new path (something like c:\Python26) to Win XP's System Environment Variable's string.

If you used the Windows installer file python-2.6.6.msi,
then the 'IDLE' IDE should work by double clicking on file

Otherwise it's your firewall setting.
