Fair enough.  Do you have any reaction to how one locates a "set of user 
interface elements" within a "software program"?  Particularly where 
that set encompasses multiple non-modal windows?  2.4.2 language has 
consensus, so we don't have to deal with the UIC question there, but 
fundamentally I see it as the same question.
