Change the registry setting makes it easier to code in the future.

HKEY_CLASSES_ROOT\Python.File\shell\Edit with IDLE\command
"C:\Python25\pythonw.exe" "C:\Python25\Lib\idlelib\idle.pyw" -n -e "%1"

Take out the -n to remove the "no subprocess" option.
You should be able to use "Edit with IDLE" as expected.
