So, basically you want to reserve that particular part of that particular monitor for the desktop preview only and would like to have the ability to prevent any maximized window to cover that area.
May I then suggest that you take a look at MaxMAx ? This little program will allow you to define an area that maximized windows can not cover. Meaning that they will maximize only in the area that you allow them.
It so happens that you can tell MaxMax that you want this to happen on a specific display (monitor).
In your case that would be the second monitor.
You can download the program at:http://www.kmtools.win-os.pl/omaxmax.php?lang=ang
Ahh, almost forgot to say it´s for free and it plays well with Dexpot.
