I have been having weird things happen with PS and when I fix one thing something else goes weird. At this point the problem is this--when I open an image into PS from ACR (I don't use Lightroom) only half of the image appears. I can go into Windows--Arrange-Float all in Windows and the full image appears. To test I did open an image from Lightroom into PS and all is good. So it's something about how ACR sends the image into PS. Any help would be greatly appreciated. I am on a Mac.
