This tip may not benefit many readers, but could be extremely helpful for a few Windows 7 users with multiple monitors.

Multiple monitors can be a helpful tool if you need lots of windows open at once, can be used with projectors, or enable you to extend your desktop onto a TV to watch a DVD.  My own PC is setup in such a way at home, but occasionally windows have incorrectly opened on the extended desktop area.  Having to turn the TV over to find them and move them is an unnecessary hassle - and takes a very brave man if someone else is watching the TV at the time!
