Why is my Microsoft Word window always on top of other windows?

For one reason or another, my Word suddenly decided to stay always on top of all other windows. This is terribly annoying. The odd thing is: of three documents I have open, two are on top of everything else, and one behaves normal.

I found one other mention of this behavior. I wonder whether this is a known bug and whether there’s a workaround. Sometimes closing all windows helps, but later the behavior creeps back. Other Office products don’t seem to show this behavior.

I’m using Microsoft Office Professional Plus 2010, 14.0.4760.1000 (64 bit).

Solution:

This single-line AutoHotKey script can be used to toggle the always-on-top behavior of the current window whenever Windows-A is pressed:

#a::  Winset, Alwaysontop, , A
