Re: [MACTCL] Command-Q doesn't quit?

[Jim I. <ji...@ap...>]

Note, originally we didn't really think that the default set of menu's  
that come up in the Wish shell would be more than a convenience.  It  
was assumed that anybody that was designing a more serious application  
would need to install their own menus anyway. So these are just there  
in order that somebody playing around with the wish shell could has  
SOME menus.

This isn't a terribly important comment, except it might explain why a  
comparatively little amount of thought went into setting up these  
menus...
