I also don't like the multi-page view when editing.  But I don't know what's going on with your Word 2007.  On my version, if I press 100% view, I automatically get a single page view.  I can make a multi-page view, but I can't make it stay in multi-page view at 100% even when I try.   
 
Have you tried selecting View from the ribbon menu, and One-Page from the zoom tab?
