I started the Photoshop free trial a few days ago in order to work on school projects, having used the program before in school. However at home, I've encountered multiple issues, one being whenever I try to crop a picture, it turns white and I can't see what I am cropping. Another problem being none of the adjustments will apply to the picture as a whole, if I select a certain portion of the image, it will adjust that portion, however when nothing is selected, I cannot adjust the picture as a whole at all. If it is a malfunction of the free trial it certainly does not inspire me to go out and spend a lot of money on the full version. Why is this and how do I fix it?
