Hello,

I have a dynamic text field being fed html formatted text from an external text file, and is set to autosize vertically (left), works no problem. I have an animated movie clip behind the text field for a background, so the text looks like it’s inside a (animated) colored box. How do I make the background movie clip autosize (vertically) along with the text box above it? I am a beginner actionscripter.

Thanks!
