Components are killing my tabIndexes ...

I've designing an accessible site. I've got tabIndexes setup for all of my important UI elements and it's working nicely: I press the tab key and the yellow box goes where it's supposed to.

BUT

I need to use a v2 textArea component (and maybe other components) on the site. As soon as I place any component in the library, all of my tab stuff stops working. It's not on stage or in any movieclip, just in the library!

What am I missing? Is there some initialization call that I need to do?

Thanks!
