I have 5 text input fields and a submit button all defined by
a tab index and it works perfectly but when tabbing to the submit
button (last in the index), the button highlights/focuses and then
loses focus after a second or two. Tabbing still works though and
you can cycle though the index over and over without a problem.
I've also noticed that if you've cycled though 2 or 3 times that
the submit button's focus remains a few seconds longer than it did
the first time it was enabled but still loses focus.
If anyone has some thoughts on this I'd really appreciate
the function of the tab key is not the same in the "test
movie" environment as it is in the regular Flash Player
environment. I only tried to implement tab key functionality once
and gave up on it, but it was confusing. I know that the Tab key is
used to assist people with disabilities and so its functionality is
built into the player (I believe all interactive content in Flash
movies can be selected and cycled through with the tab key).
