Welcome to our community, Gayle
Perhaps you might consider using a frameset to present your
Captivate. You could have one frame displaying the Captivate and
the other displaying the page the user will manipulate.
Maybe someone else has a better idea and I really hope so,
but that's about the only way I can fathom providing this
functionality. Captivate doesn't really offer anything that would
allow it natively.
Cheers... Rick
