Alt+Space to open up the window's control-menu box, then keyboard selection for "Move", then arrows or mouse to move it. May also have to resize it.

Assuming, of course, that this is the problem. Maybe it's not the problem and it's totally unrelated. It's just that your symptoms are consistent with this trick, assuming that Word even LETS you do this trick. Dunno if it does, some apps are smart enough to disregard the window-position settings if they're too far offscreen.

But I remember a computer-tech friend of mine describing how a customer brought his Windows 3.1 computer into the shop saying File Manager wouldn't work any more. He had those exact symptoms with File Manager, and it was because of that trick.
