I was working in Photoshop yesterday and all of a sudden I can't move anything around with my mouse, only the arrows. I have tried resetting preferences, opening and closing the program, restarting my computer and searching online since yesterday for an answer or way to fix it. Nothing seems to work... I think I must have accidently selected/deselected and option that disabled my mouse actions. I can move the arrow around and select the items but I can't drag them. I have a laptop with a built in mouse. What do I do?
