Hi Mark,

First of all, please notice that Nabble is just showing the idle-dev
mailing list. However, when you mail me directly, your questions
aren't sent to the mailing list, which is too bad since your questions
and our answers may be useful to others in the future. If you have
further questions regarding IDLE, I urge you send them directly to the
mailing list: idle-dev at python.org.

Now to "business". I don't quite understand what you're trying to
achieve now - are you still trying to make double-clicking a Python
file open that file for editing in IDLE?

If so, you should start by learning how to change what Windows does
when you double-click a file of a certain type. (look in Control Panel
-> Folder Options -> File Types) My guess is that Windows lets you
choose an executable, and then when you double-click a file of the
appropriate type it runs that executable with the file's path as the
first argument.

Once you've figured this out, you'll need to make such an executable.
You can use a batch file much like idle.bat (found inside
Lib\idlelib), changed to use absolute (full) paths, like so:

@echo off
start c:\Python25\pythonw.exe c:\Python25\Lib\idlelib\idle.pyw %1

Save this with as a .bat file somewhere, and then tell Windows to use
this .bat file to run .py files (in Folder Options).

I just tried this now, and it works like a charm. Good luck!
