I have 2 dynamic text boxes that are embedded in a movie clip, which I'm fading in using actionscript.

All the content in the movie clip fades in, but the 2 text boxes just imediately appear on screen.

This is the code I'm using.

Code:
new mx.transitions.Tween(_parent.patients, "_alpha", mx.transitions.easing.Regular.easeInOut, -100, 100, 3, true);
I've tried putting the code and that text boxes at various levels of my movie thinking it may be a nesting issue, but nothing seems to work. Also changing other attributes, such as position on screen, but that doesn't work with these text boxes either. Even tried putting a mask over the boxes and animating the mask, that cause the text to disappear entirely.

The same or similar code is working without any problems on other elements in my movie.

At this point, I don't really care what it does or how I do it, I just need the text to animate in some how, instead of just plopping into place.
