The .pyw works, for Idle!  :woot:  I have a glaring unfamiliarity with the .pyw format.  If a lack of familiarity can glare.  :unsure:  Never seen the type before.  Huh.

Poser Pro 2014 will only allow one to browse for a .exe file, when attempting to set the Python editor in the user preferences, on Wndows.  I had to edit the Poser.ini, in order to set up Idle.

PYTHON_EDITOR_PATH "C:Python27Libidlelibidle.pyw"

(I note that we apparently can no longer post text on Rosity in code brackets.  Feh.  We can certainly format text with plenty of color options, however....  :unsure:)

When I open Idle from within Poser, however, I get the correct Idle window, plus two extra instances of Idle.  One is named "Pro" and the other is just "Python Shell".  These are irritating, but can simply be closed.

Whoa.  Make that four extra Idle windows, and I don't remember the names of the last two.  Might have been "Poser" and "Micro".  Kind of goofy.  Don't like that it does this.  Hmm.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
