Have a Lumia 800. In Office I have an accumulating display of word tile-icons. Cannot find way of deleting. Have lodged this problem a month ago with 'Nokia Support'--there's an oximoron for you!! Still no resolution. Opening the document, then touching the dot-dot-dot option doesnt give a delete option, whereas doing the same in One Note does. Am ending up with an accumulation of redundant tiles.
