Hot corners have stopped working for no apparent reason.

    It's done it twice so far, once yesterday when the dock also became unresponsive, only a hard reboot would fixe the issue, I couldn't even use the apple menu to restart the computer.

    Just now hot corners have stopped working completely. The only difference from 5 minutes ago is that I disconnected my external display, and installed flash player 10.1 pre-release.

    Any suggestions? I'm using both the trackpad and a bluetooth might mouse, both do not trigger my hot corners.

    Edit: I plugged my external back in and unplugged it again, and now everything works. Odd.

    I usually get this problem when plugging and/or unplugging my external monitor too. Usually fixed by opening up Terminal and typing:

    killall Dock

    Works for me, so hopefully it works for you!
