Consider what happens if I'm busily typing away, and the dialogue box
pops up and grabs focus, and then whatever its default is gets selected
because i hit space or enter. So not only have you annoyed me by
popping something up and then removing it before I get a chance to read
it, you'll now take an action without the user knowing about it but on
the assumption that he does, *and* you've eaten an arbitrary amount of
what I typed, which I'll have to type again.
Needless to say, this is a Very Bad Idea.
