MS Word 2011 Book View Problem

Hi,

I have a macbookAir...OSx10.7.5. I've been using MS Word 2011 14.4.1 for a long time. I've always had a 1 page view.

I must have clicked on the wrong thing...now I have a 2 page side-by-side view of every Word doc I open.

I went into Format-Document-Margins....the view shows "Whole Document"...and Mirror margins is not clicked on.

When I start typing and go to the 2nd page I continue to get the side-by-side view.

Any ideas...

Thanks....Ken
