I don't think this has been reported before.
RightClick doens't work properly with Matrox PowerDesk.
The reason I'm bringing this up is because I see it as immensly beneficial if they would work together. Let me explain...
PowerDesk is a useful tool used by many people with more than one momitor. It controls in which monitor the program windows and dialog boxes open, and it enables windows to maximize to a single display and not the whole span (among other things). The thing is that when you work on a large display area, it can be quite inefficient having to move the mouse to a fixed place in order to access the program menu. (Especially if you work on 3 monitors.) This is is where RightClick comes in, it is such a crucial feature having the program menu ready on a right click. But, the problem is that PowerDesk regards the RightClick menus as program windows which it then relocates to another fixed part of the display. This makes it impossible to use.
(Actually it doesn't relocate the first appearing menu, but the consecutive ones.)
So, the solution will have to be one of two things:
Either Matrox makes an exception list where the user can add programs that are not going to be affected by PowerDesk,..
or Stardock reprograms RightClick so that its menu windows are not affected like program windows.
