I think you may have hidden the white space above and below your doc. Let's find out. Immediately after opening Word, choose Print Layout view, choose Whole Page from zoom pull-down menu. If your doc looks clipped, place your cursor below the page and it will turn into something other than an arrow or I-bar. When you see the change, click. This will show hidden white space on your page. Go to 'File', 'Page Setup', adjust your margins to what you always want Word to open with then click the 'Default' button in lower-left corner. This should solve your problem.
