Pages showing side by side rather than vertically

While in page view of a score, the pages are stacked vertically so that if there are 5 pages you would scroll downward to get further into the notation. Is there a way to get the pages to be horizontal so that I'd scroll or page grab with the mouse to the right for the next page rather than downward? I don't mean to go into continuous mode, I mean to stay in page mode but see the pages as if they were in a sort of book-type form from left-to-right.
I'm probably over looking something simple, and I vaguely remember this being the way it was when I first started working with the program, but I could be mistaken. Any help?
