All of that's true, HarryT, what I meant was that PDF is a perfectly fine format
for its designed purpose. It works okay for the Reader if it's formatted properly, but it's still pretty rigid. If somebody's more comfortable with that, then more power to 'em.
Of course, as you and I both alluded to, none of that applies to the
Excel 2007 Bible that was referenced in the original post.
