Controlling Dynamic text Scroller

Hello Everybody,
I have a question maybe someone with experience can push me in the right direction. I just upgraded to MX6 so i am learning my way around, I was using V5 before this so it’s like starting from scratch almost . . .

Anyway . . . I dropped into a dynamic text field the scrollbar generic to MX.
The scrollbar is great but what if the text is not long enough to need the scroller.

Why use the scroller you say . .? Well the website is for someone who is going to be changing the text dynamically as they need to, so right now th scroller is useful, but next week if they upload a two line document, the scroller will be redundant . . .

has anyone run into this before . . Thanks in advance you all . .
