Hot Corners Stopped Working on Mac OS X
Like many Mac users, I use hot corners to start my password protected screensaver when I'm ready to walk away from my desk. Seemingly out of the blue, I was unable to use hot corners any longer. I tried changing the settings, added another hot corner, etc, and nothing seemed to work. Finally after much googling I found a thread on apple.com with other people having the same problem. Most of the solutions said to reboot which I didn't really want to do, but eventually someone else found a way to fix the problem:
- Open up Activity Monitor
- In the search filter type
- Select the item in the list who's Process Name is
- Click on
The Dock and Expose will be restarted and the problem should be solved.
Give that a whirl and hot corners should start working again for you.
