Keeping windows on top

[Demious]

Since I couldnt find a P3D section and P3D is the follow-up for FSX I didnt know where else to post this then in this topic...

I'm working with 2 monitors, on top of eachother, on for my outside view and one for my cockpit. Since I cant move my view in the main panel window, I have to put another window on top of that, with the panel that is on the ceiling of the aircraft. However, everytime I click my mouse on the main panel windows, the window with the toppanel is moved to the background and I have to move the main panel window aside, to be able to move the top panel window to the other monitor, put the main panel window back and lay the top panel window on top of that again.

Is there a way I can lock the windows possitions, so I can click in the main panel window, without the top panel window being moved to the background?
