All of my Internet browsers and the Mac App Store seem to only load pages for a few seconds and then become entirely unresponsive. When I command Q to quit, the application closes, but the dot remains in the dock so that I have to force quit. I have restarted many times and tried repairing disk permissions. Has anyone ever heard of this?
