It's there on my MacOS X 10.6.5 system.

If your 10.7 system doesn't show it, that's definitely a bug.

As a work-around, you could name the your file xxx.pyw.

On Windows, there's a functional difference between .py
and .pyw.  On a Mac, there's no functional difference and
Idle is willing to open both types of files, so you could
use .py for code and .pyw for data.

If you're feeling adventurous, you could try solving it
yourself.  Idle is written in pure Python; that makes
this sort of thing a lot easier than if it were in C.

And bug reports with a patch are far more likely to be
picked up by the dev team.

Hope this helps,
