Scrollbar question

Hi folks. I am building a site that imports text, and I am using the Flash scrollpane to display the text. Of course, the scrollbar component gets automatically applied if the text is too long, which is great. It acts just like it normally should.

The problem is, my designer is insisting that the scrollbar *not* resize to match the text, which is completely outside the way most scrollbars work, and is like older flash scrollbars that were built by hand and not components.

Is there a way to make a scrollbar component not resize and just determine a set size for the scrollbar? Thanks.
