It looks like when I am using almost anything in Office that my desktop icons get rearranged.

I have about 25 icons in which I have to search to find what I want after I use Office. It makes no sense to me. It can be a newly created icon or one that has been there for months but one, two, sometimes as many as five will get moved. This is especially evident if I leave NS Word open on teh screen and walk away for a few hours. It is almost predictable,

It doesn't seem to matter if I had created or moved the icon recently but I will have to look for it among the masses...
