CS3 UIScrollBar Component not working

Hi, I’ve searched around the internet, trying to find a solution to this problem, and have yet to be able to find a good answer!
So I’m using the UIScrollBar component (CS3 Component) for my long text boxes. It’s nice and easy, and works absolutely fine in the Flash authorizing environment. My problem comes when I publish the files online. I have tested this on multiple computers running different operating systems, different browsers, etc… No matter where you view the website from (it’s for a website), the scroll bar does not show up! It’s not that it’s there and greyed out, it’s straight up not there. This is true for both in-file text (text typed directly into the text box) and dynamic text (loaded from XML).
If I test the .swf in the Flash environment, it works fine, it’s only when in a browser! I have no idea why it’s not working, if someone has a solution please tell me. Should I be using the UIScrollBar? Should I make my own Scroll Bar component (and if so, a nice tutorial on how to do this)? Should I attach them via Actionscript?
Thank you in advance for your help!
