Setting defualt font in Tkinter

[Norman Charnley]

Is there a way to change the default font in Tkinter for all applications
(using Python 2.1 under RedHat Linux 7.1)? 

I know I can set it specifically when I am creating widgets, but it would
be useful to have the default a little more readable. 

In particular, when I fire up Idle, the menu font (not the editing font,
which IS configurable) is awful, and although I can mostly fix it up by
poking about in EditorWindow.py, that seems a messy way to have to go.

Thanks in advance for any help....
