Maximum Amount of Text in a Scrolling Panel

I have not yet received a response from my initial post on this same question:  http://community.articulate.com/forums/p/16712/95025.aspx#95025

This is an important issue for me as I am trying to add captioning for a video and if this will not work, I'll have to go a completely different direction and I need to have this project done by tomorrow.  Any help that could be provided would be greatly appreciated!
