Donna, when you view your images (I assume they are all raw files?) in Fast Stone, they are all there? And when you click on e.g. one image in Fast Stone, that one opens in ACR correct? And does it also show on the side? But when you click Shift + Ctrl (on a PC) and select several images, and then click Open in ACR, they won't show in the left panel on the side? What if you "scroll" through them in ACR, are they there? I'm attaching Snipping Tool image of what I mean....
