Hot Corners stopped working at startup

Same problem. Screen saver stopped working. Hot corners don't work. 10.5.2

Same problem here. Are hot corners really broken in Leopard? Does anyone have a solution for this?

I installed Leopard in December. Hot corners kept on working since then. I have been running 10.5.2 and they worked.

Until today. Mine have stopped working, somewhere today or yesterday. Haven't investigated further yet.

Hot corners randomly stop working on me all the time. Pity that Leopard was the operating system which broke such a fantastic feature.

After a little experimentation, I discovered that Hot Corners -are- working, it's the Start Screen Saver that doesn't work. I can cause the display to sleep, and other Expose functions, but not the screen saver.

Can someone else confirm?

I used to use this to step away from the Mac and lock the machine without logging out. Is there another way to do that, even if the screen saver isn't activating?

I can confirm that behavior. Hot corners work for me on other actions (such as display sleep), but not for initiating the screen saver. This would not be as big of a deal for me if the 'sleep display' action required a password to wake from, but since it doesn't, there's effectively no way for me to lock my screen when I step away. Even the keychain menu item 'lock screen' won't work.

Only a restart serves as a temporary fix for me.

lostintrns - try completely disabling Spaces. That is, don’t just uncheck the Enable Spaces box, but remove all the applications from spaces.

You might want to make a note of which applications you have in which Spaces. If it doesn’t help (which it very well may not because it would be hard to believe all the people above are running Spaces), you can then re-enable your Spaces.

If it does work, you may be able to re-enable Spaces because disabling it may reset something that will allow your hot corners and Spaces to play nice together again. If not, you know the problem is with Spaces.

Thanks for the suggestion Bruce. I will try that. Can you tell us why you suspect Spaces as the culprit?

Two things I can think of.

One, with Spaces enabled, if you grab an application window and drag it to the edge of the screen and hold it there for a second or two, it will move that application to the next Space. Try it- grab your browser window and move it to the Space to the right or left.

When moving to a hot corner, perhaps Spaces is confused and thinks you are trying to change Spaces, thus never invoking the hot corner function.

The second is, someone reported on this forum that he changed the key-combination for moving to the next Space from Control-arrow to Command-arrow. Then he figured out that in his word processing program and Mail, Command-arrow is used to move to the beginning or end of a line. When he went to Spaces and changed it back to Control-arrow, so he could retain the end-of-line function, it didn’t fix it.

I suggested he remove all the Spaces applications and then try it again. It worked for him. He was then able to re-enable Spaces and had his end-of-line key combination back.

That makes sense. Thanks for the great idea and explanation!

For me a repair permissions & reboot fixed it

But I did notice that the 'album art' screen saver blinks the lower left corner after turning it. My lower left corner has 'disable screen saver' (and lower right has 'start screen saver').

Seriously....

a) This is not a Leopard bug because it happened to me on Tiger too.

b) Therefore, it has nothing to do with spaces (directly)

c) Repairing permissions and rebooting is not the "fix" it's just the rebooting.

d) I shouldn't have to reboot

e) Definitely a bug.

a) Open up Activity Monitor (/Applications/Utilities/Activity Monitor)

b) In the search filter type "Dock"

c) Select the item in the list who's Process Name is "Dock"

d) Click on Quit Process.

The Dock and Expose will be restarted and the problem should be solved.

My Hot Corners completely stopped working for all actions and my ability to move specific screens from one space to another. This all happened after I installed the latest OS updates yesterday. I tried quitting the the dock, repairing permissions, rebooting, disabling spaces, etc. Nothing works. Help. It really seems like it was the update that took me out.

Talked with Apple Support. Level 1 could not help. Level 2 suggested Archive & Install of OS. Did that today. Hot Corners still do not work. I tried them before installing all of the OS updates. Have not had a chance to call back yet.
