I wanted to copy a girls face from one photograph and paste it on to another. I checked that all layers were unlocked. Added the required mask, as in the video, as I progressed. Made a selection with the Elliptical Marquee Tool. Used Ctrl+C. Went to the other photo and pasted, Ctrl+V Up to this point there were no problems.
Tried to click on the white arrow of the Move Tool but it was not working. No change to it just did not respond to my clicking. I tried the keyboard V, nothing. I then noticed a Windows green bar above the program telling me the program had stopped working. Closed down and started again, several times, with the same result. Any advice would be welcome. Thanks.
