On my old machine, if I highlighted 4 JPGs and right clicked and chose Open, it would only open one instance of Paint Shop Pro with all 4 pictures in that one instance. On my new machine, if I highlight 4 JPGs and right click and choose Open, it open four instances of Paint Shop Pro, with each instance only having that 1 JPG in it. How do I set Windows explorer to only open one instance of Paint Shop Pro with all 4 JPGs within that instance?
