Hi! I need a function or some other setting that would keep my GUICreate within visible desktop area, when there two or three displays. I can find RED values with the DllCall, however I cannot find underlined values. Point on the program is to show current background images from all desktops, so that user would be able to move liked background to favorites. (In my case I have 150000+ images in slideshow every minute, and this program help to sort though these images) Program creates GUI/s
