Corners stopped working

My corners have suddenly stopped working. When I go to System Preferences-->Expose-->Active Screen Corners, they're still set the same way they were before they stopped working. Help!

Hi David!
That sounds really strange. Can you think of anything you might have done/changed on you mac before the hot corners stopped working? Any new applications installed, for example?
Maybe a resart might work, if you haven't done that already. Also, try using Disk Utility (found in HD>Applications>Utilities) to "Verify Disk Permissions" and "Repair Disk Permissions" on your Hard Drive. That might sort out any little bugs which might be stopping your hot corners from working.
I take it, that your 'Hot Corners' Preferences are properly set to what you want? What ahppens if you put them back to "Nothing", restart and then put them onto what ever triggers you want?
I hope that helps!

  • Hot Corners Stopped Working

    Strange, up until yesterday my hot corners were so sensitive I was constantly activating them accidentally; now they are not activating at all.
    System Prefs>Desktop & Screensaver>Hot Corners is not doing it for me! Reboot?

  • Hi, my name is Amit, my hot corners stop working after some time. Have to go to mission control to reset them, however they stop again after some time. This is annoying. Can someone please assist to solve this problem? Thanks Amit.

    Hi my name is Amit, after upgrading to OS X Maverick I often have problem of my Hot corners stop working after a short period of time. I have to go to mission control and have to reset them for them to start working again. However this is temparory and they stop working again and this is quite annoying. Can someone suggest a cure to this problem please. I will be grateful. Thanks Amit.

    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    ~/Library/Preferences/com.apple.dock.plist
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item selected. Move the selected item to the Desktop, leaving the window open. Log out or restart the computer and test. If there's no change, put the item you moved back where it was, overwriting the one that may have been created in its place. Log out again. Otherwise, delete the item you moved.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

  • My two right hot corners stopped working

    The two right hand hotcorners of my Macbook Pro stopped working 2 days ago. The left hotcorners work fine, as the right ones did, but suddenly nothing. I already tried the thing with erasing the dock file from the library and restarting the laptop, but it didn't help. I'm a little frustrated,,,is this a bug or what?

    Try a SMC reset:
    http://support.apple.com/kb/HT3964
    Also go to system preferences>Desktop & Screen Saver>screen saver tab, in the bottom left corner click hot corners and see if they are blank, somehow it was dumped and try resetting them to your preferences.
    Try this before the smc reset. Sorry I had to fire up my Lion machine to check this.
    All the best

  • Help! The secondary click on my trackpad for right and left bottom corners stopped working after 10.9.3 update??

    MacBook Air 11" 2013...did the OSX update for 10.9.3 on 5/17/14 and my secondary click on my trackpad just stopped working. Checked the system preferences and tried the other corner found it doesn't work for either bottom corners for secondary clicking. It will pull up the secondary click menu when I have the "two finger tap" option selected, but I don't use that one at all, it's not a natural function for me.
    I tried doing a hard reset 3 times and that didn't do it. Then I reinstalled the combo update for 10.9.3 and that didn't work either....
    ... ..any ideas?? 
    -lost without a secondary clicker

    The full release of 10.9.3 is available from App Store now. You can re download the full version from your Purchase tab in App Store. After download there will be Install OSX Maverics in Applications folder. Before installing OSX on top of the one on your system, copy the a install aoSX Mavericks to your external drive or any location. You can copy it to Applications folder for reinstall after that if you want.
    The new download will be 10.9.3. Before doing so, please try to boot into safe boot, by holding shift key and power on. Try your secondary mouse click to see if it work. If it is the same, then it will be driver corruption, try reinstall will help.

  • Active Screen Corners stop working without complete restart

    Since I installed Snow Leopard, I've noticed a problem with my active screen corners not working. I usually only completely restart once in a while, so I usually just shut the lid at night (or when I go anywhere). with 10.5, it used to be that active screen corners always worked when I did that, but since I installed Snow Leopard, active screen corners quit working. I have to completely restart to get them to start working again.
    Is there a way to fix this, or is it a bug?
    Thanks.

    I tested this with a few system applications, if it helps anybody.
    It also might be interesting to note that in all cases where expose won't trigger, the dock won't unhide by holding the mouse at the bottom of the screen either so long as any of the non-working applications are selected.
    List of applications that also have this problem on my system:
    Textedit
    Activity Monitor
    iChat
    Calculator (Unlike the other applications, the active corners don't even work on this the first time)
    List of applications tested that are NOT having this problem:
    iTunes
    Safari
    Terminal
    Mail
    Address Book
    Photo Booth
    QuickTime
    Automator.
    Does anybody know if the applications that are not working have anything in common? Conversely, could anybody confirm that they are NOT experiencing this problem, and that it is specific to certain system configurations, or perhaps even my system?
    Thanks in advance,
    Kevin

  • Hot corners stop working with USB Mouse?

    Hi,
    pretty simple one this (to explain anyway)
    Hot corners don't work with a USB mouse on my 10.10 MBA.
    If the USB mouse is plugged in, hot corners do nothing (Whether I use the mouse, or the track pad to move to the corner of the screen)
    If i unplug the USB mouse, they work fine again.
    I have rebooted and unplugged and replugged the USB mouse to no avail.
    Any ideas?
    Thanks!

    Have you tried another USB port?

  • Compiz corners stop working

    And that's it. I have every corner of the screen attached to a function: expo, scale1, scale2 and show desktop. It works fine for some minutes after logging but suddenly corners don't trigger anything anymore. I have to deactivate it in compiz and activate it again.
    Google doesn't show anything...
    Thanks in advance one more time...

  • Hot corners regularly stop working

    My hot corners are correctly assigned (from the previous OS) but always stop working after a while. This is corrected by a restart. Guessing that this is a bug in Mountain Lion and wanted to bring to your attention. Thank you.

    Try this. In the Finder menu bar click on Go > Go to Folder and type ~/Library/Preferences. Highlight com.apple.screensaver.plist and remove to your desktop. Logout/Login or restart and reset screensaver preferences in Desktop & Screensaver in System Preferences. Click on the Hot corners button and reset your hot corners preferences. If this works you can trash the Preference file you moved to the desktop.

  • Hot Corners and Keyboard Shortcuts Stop Working

    When disconnecting from my 27" (that I use as a docking station with keyboard and mouse), in some cases my hot corners and keyboard shortcuts stop working.
    F11 does not show the desktop, Ctl-UpArrow does not show mission control. Ctr-left-right arrow does work, as i can still toggle between desktops.
    I know, lots of randomness here...
    A reboot fixes everything.

    I've go a Windows 7 system running CS5 and when I start Photoshop all my shortcuts are working but eventually really important ones like the brush tool sizing stop working. At the moment the only non-adobe/windows app running is iTunes and that have been running the whole time, turning iTunes off does not enable the stortcuts again.
    Has the only conclusion to this problem been to turn off other apps? This has been a problem for me since I upgraded to CS5 and its driving me a little mental !

  • Hot corners for screen saver and sleep stopped working

    All of sudden my hot corners don't seem to work.  They were fine the last time I tried to use them.  I place the cursor in the corner and nothing happens?

    I shutdown the system and tried a different keyboard and the hot corners worked!m  So I shut the system down again and hooked up the possibly bad keyboard and the hot corners also worked.  The only other thing I had done was to disconnect the logitech receiver for the remote mouse and tried to use the mouse with the older keyboard.  I neededto hook up the logitech remote mouse again, because the system would not recognize the old keyboard mouse.  So somtething happened, but i'm not sure what.  I'm back to good for now.

  • Help! My screen saver stopped working?

    2013 iMac
    3.1 GHz i7
    16 GB DDR3
    OS X 10.9.3 (13D65)
    My screen saver stopped working about a month ago.  I tried resetting the PRAM and it worked for a few minutes, but then it stopped.  I tried using Hot Corners, but it starts and then turns off after a few minutes.  I am able to make it work if I turn Airport OFF and disconnect the computer from the internet.
    What are my recommended next steps to get the screen saver back to normal function?
    Thanks for any and all help.

    We are going to delete a hidden file.
    Finder > Go Menu > Go to Folder and type or paste
    ~/Library/Preferences
    and scroll down until you see
    com.apple.systempreferences.plist
    drag the one you can (may see two) to the Trash, reboot, reset your System Preferences again.
