Cropping tool makes my photo disappear
PS4 - version operating on OS10.9.5 - I have been using CS4 for many years with no problems and then out of the blue working on .psd photos I went to crop the frame but when I pressed 'return' the image box minimised to about 1" sq and the entire image disappeared, however it was still evident in Bridge. After expanding the box I quit it without saving. I changed the name on PS4 and reinstalled the program. I even tried reinstalling the program from Time Machine. I cannot get the function working.
