Very odd. I've been using the most current version of El Capitan with no problems. I wonder if you might have some file permission problems? I know that El Capitan is supposed to correct permissions automatically but I wonder. I run a program called Cocktail just to be safe. It seems to correct permissions and clean caches. I wonder if you might try something along those lines?
