Is there a scrolling text box option that I'm missing?

Scrolling text boxes are not great for user experience.

A better idea would be to make the page longer to accommodate extra content.

Agreed. I try to avoid them if at all possible.

That works better. :-)

Thank you all! I hadn't even thought of making the page longer ... that's certainly the easiest to do, and might work best.

If that doesn't pan out, I'll try the .xar file you were kind enough to post.
