Disabling scrolling of Acrobat document

I am looking to create an interactive presentation (using Acrobat) that allows the user to navigate through a series of pages using simple Yes/No branching - no problem here.

I am using the link tool to jump to the relevant pages dependant upon response, with the document set to display in full screen viewing mode with all toolbars and menus hidden. The problem that I am experiencing is that Acrobat allows the user to scroll (page up/down) through the document, this obviously negates the branching navigation! - Is there any way to disable this feature?
