Some time ago I used to get a bit of fun copying a selection from one image, such as a face, and pasting it onto another image. I would then use the 'hand tool' to reposition the pasted selection to the exact spot I wanted it to be.
When I attempted to do this just recently, using both Photoshop CC and Photoshop CS6, I was unable to move the selection, even though the layers had not been flattened. Something appears to have changed with the constant upgrades to Photoshop.
Can someone please advise me how I can now do this. Is there some new setting I have to enable?
