That's how it is supposed to work. But I remember that Delphi controls were
based on Windows controls too, but they weren't recognized by at least one
screen reader. But this may be this specific screen reader's fault, which
maybe did not gather information using the Microsoft recommended method.

Yes, of course, I forgot about that :-P

This particular situation is what I was trying to draw attention to :-)
