I'm running CS5 with Yosimite (mac). For several days, I've had problems. When drawing, CS5 decided I wanted to rub out. Today, I want to draw in black, but it's only letting me draw in red. Usually shutting down photoshop and restarting my computer clears this. Not today. I've even uninstalled CS5 and reinstalled. I can still only draw in red.
Help!
