Nice, good catch.

I had the same problem. After searching the entire registry I found the problem was with the following key:

[HKEY_CURRENT_USER\Software\Classes\Applications\python.exe\shell\open\command]
(default)=”D:\Python26\python.exe” “%1″

I changed it to:
(default)=”D:\Python26\python.exe” “%1″ %*

Python scripts now take arguments from the command line without ‘python’ at the beginning. That key was overriding the settings for Python.File.

Very frustrating, eh?

The problem I had was that it doesn’t pass the command line arguments if you don’t have “python” at the front.

So for example, this doesn’t work for me:

myscript.py argument1 argument2

whereas this does:

python myscript.py argument1 argument2

I don’t know if this is a related problem or not.

Thanks, that worked great.
