I've laid out my XWD window so the main window XWD window takes up most of my screen, just to the right of the main window I have the "Page & Layout Gallery" and when my browser window is open I can just see the edge of the "Page & Layout Gallery" but when I click on it the XWD windows will not come to the front of my screen.

I'd like to suggest that when any XWD window is clicked then all of the XWD windows will come to the front of the screen.
