I'm thinking of using powerpoint to make a hifi-prototype that would have a windows 8-like feel. I would like to be able to scroll horizontal within the slide, is it possible to do that with powerpoint? I'm thinking if there is some scroll-box function I could use or something.

I would also like to have a fixed menu at the top and bottom of the "app" which means only the middle part of the screen should be scrollable. Is this possible with powerpoint or should I use microsoft expression studio instead?
