Are you clicking on the desktop of the 2nd display, or a window in that display? It works for me. Another method for capturing a window is Command-Shift-4, then press the spacebar and click on the window. That should work, no matter which display is involved.Hi .. I have two screens for my iPad ... Everytime I take a screenshot, it takes a picture of the screen to my left. Even if I put the cursor in screen two, doesn't matter ... Anyone know of anything to help this???
