P: Hiding sometimes makes it irretrievable

Multiple times per day when I hide Photoshop (command+h), go to do something in another application, then click the Photoshop icon in my dock, Photoshop won't come back. I can right-click on the icon and select "Show" but it won't come back. I also use hot corners, but when I mouse over to show all application windows, it says "No available windows." I have to quit the application and restart it. I can right-click and select "Quit," and it will work, rather than having to force quit. Then it will be fine for a few hours before it does it again. I am running Mac OS 10.12.4 and recently wiped my computer to reinstall CC applications because they were all lagging. (SO much rainbow wheel.) Since doing this, I've encountered this Photoshop problem.
