Users of traditional HTML forms have gotten used to tabbing through the input fields to enter in their data. Users will do the same thing in Flash, but Flash tabs to elements on the page that we don't want to bother with. This is because, in HTML, a form is bounded by the
tag, while in Flash, there is no "form" section -- it's just all movie clips or in the _root timeline. Flash doesn't know any better, so we have to make it a bit smarter -- and meet the user's expectations.
