I'm on PSE 12.1 and the software crashes constantly. I'm currently working on a 600 + personal job. About every fifth shot when I try to open the editor I get these messages: "Could not complete your request because PSE does not recognize this kind of file" and "The command could not be completed because the editor was busy. Please finish the current operation and try again." I will click these two irritating messages off and immediately try again; sometimes it takes two or three time cycling through these two screens before the editor works again. In addition, sometimes it freezes up entirely requiring me to force shut down my computer. Finally, I experience what I've dubbed runaway pictures. If I move the curser across the screen to get to a button, the slides fly through the organizer, landing somewhere else and causing me to re set the picture. More irritation.
