IMHO, you really don't want to do this if you can avoid it. Questions like
"Are you sure you don't want to avoid quitting and exit without not saving 
your file ?", with buttons labeled [Yes] [No] [Cancel] are often confusing,
and waste a users time by forcing them to check carefully whether they
should be clicking [Yes] or [No].

It is *far better* to have boxes like, 'Ran out of wigets to twiddle...' with
buttons [Make More] [Stop Run] to click.

I would think that it isn't going to be too hard to dynamically create 
dialog boxes like these if there are too many to use IB. Unfortunately, I'll
have to leave it to someone who knows how to tell you more...

I would think that there ought to be something about not having [Yes] [No]
buttons in the user interface guidelines. If there isn't, IMHO there should 
be... (Are you listening comp.sys.next !! ;-)
