A while back (maybe 2 or 3 updates ago - running 2017.1.1) I suddenly had a problem with dragging a PSD watermark onto a JPEG image. It shows up in History as being being there (top layer of the JPEG) but it is not visible on the image. If I use CS6 with the same 2 files it shows up just as it should. All the settings appear to be the same whether the watermark and JPEG images are opened in CC2017 or CS6. Any suggestions?
