Doug this is probably a totally stupid newby green question to ask, but,
why, goodness me why, for such a seemingly so regularly needed and useful
type of functionality, wouldn't there be a more elegant way in jaws of
locating a given window?
i guess there *must* be a technical reason other than mere short-sightedness
on the part of the script language creators, but, is there?
or is it just like the whole Aray thing, which it took till jaws 11/12 to
even introduce, when I remember people had been ruing the lack of such an
apparently normative programming language feature, for years before that.
