This handy tweak fixes a problem that has bothered me for a long time, and can be used with any Windows app, not just FF games.
Running games in fullscreen prevents you with doing other things on your pc properly, is slow and causes flickering when going in and out of window focus, and is a nightmare for people who use multiple monitors like me.
On the other hand, running the game in a window at full resolution doesn't fit the screen because of the Windows title bar.
So the solution I have found is Gamers Window Relocator. You can grab it here:
http://gwr.orekaria.com/GWR is an application intended to fit the window of a running game so that you do not see the title and borders (even when they really are there).
For optimum result, you must configure the game to run in window mode with the same resolution as of the screen
GWR works with one or more screens. When there is more than one, the window is fitted to the nearest screen corner.
