recently while using Photoshop CC, after about 2 min - an hour of using it. my keyboard completely stops working, only with this program, i've taken my laptop to apple and from their end everything looks fine. i re-installed my intire computer but still having problems with photoshop CC. uninstalled Photoshop CC and re-installed it again. and after a half hour my keyboard stopped working. and even after i save and close my work with the mouse, the keyboard won't work till I restart my macbook pro. with college having just resumed, I can't have my computer being repaired at apple. and I was walked through how to see if it's a hardware problem and it didn't seem to happen on a guest user, so it must be software problem. could you please advise what i should do?
