hot corners not working

Rebooting and resetting permissions seems to help briefly, but after a few minutes, Hot Corners stops functioning again. This is clearly a bug which Apple still hasn't bothered to fix.

hot corners quit working, disgusted with Lion after 3 clean install system crashes... worst Mac OS version so far. For everything good, it's all negated by overall glitchy nonsense, the basic funtionality of most system features are broken, even the finder is laggy and flawed.

Hi,

I think hot corners not working if wineskin starts working.

without opening it.... hot corners seems to work fine...

Try it out..

What exactly do you mean? Wineskin shouldn't affect teh corners unless your running something thats using fullscreen, then it captures the whole display, and yes, hotcorners and many other things will not work... but thats intended as fullscreen usage is for gaming. You can toggle captured fullscreen with anything ported with Wineskin by using Cmd+Opt+A if you need to multitask some.

Hot corners (including the F3 button) are still not working for me - kind of driving me insane. I paid for this upgrade to Lion and do not think it's my responsibility to do bug fixes on my own time. The whole point of buying this was to NOT inconvenience me... Has anyone had good luck with talking to Apple reps? I'm calling them today to see what I can do.

Just recently started having this issue. I was getting completely torqued about it, and not satisfied at all that I had to do ANY kind of coding (my word for 'being treated like a Windows user') to fix this. I didn't buy a Mac (several actually) to have to do this for something so basic.

But I digress... I play a game that uses wineskin. temporary fix until I get the bootcamp loaded with windows. played the game for a couple of days, then my Hot Corners died with no fix in sight. HOWEVER COMMA!! I saw doh1231's comment about CMD+OPT+A...

1) started the game, cmd+opt+A'd to windowed mode, tried the corners = WORKS!

2) killed the game with cmd-Q, tried corner = WORKS!

3) restarted the game, it defaults to fullscreen mode (cmd-tab stops working too... grr), killed game = NO WORK!!

4) restarted game, cmd-opt-A to windowed mode = CORNERS WORK

5) killed game = CORNERS WORK

so for ME, this was enough proof that the wineskin was the wrench in my works.. I don't know how or where, but now my corners work, and I know where the culprit is if they stop working again...

Hope this helps!

Thanks Dan - worked like a charm!

This tip worked fine for me. Thanks Dan! I just had to arrange my Dock again, but that was a minor inconvenience. Hot Corners are back! 😉

10.7.1 update seemed to have solved this for me.

However, for those still having Hot Corner issues, here's something to try.

Go to your Finder and press Cmd+Shift+G and enter ~/Library/Preferences . This will navigate you to your user library/preferences folder.

Move the file 'com.apple.dock.plist' to your trash and log out and back in. Your dock will most likely need to be reconfigured and reorganized as well as your Mission Control settings. This should reset dock and Mission Control settings to the user default and hopefully will clear up any bugs in those preferences. Set your Hot Corners and see if they stay set for good this time.

+1. Lion hot corners stop working. Tried all of the remedies mentioned here. (Permissions, created new login, plist edit...).

Logging on & off fixes it for me(i.e. no need to reboot).

(As an aside -since upgrading to Lion on my mid-2010 MBP, I've had more spinning beach balls, freezes/reboots and odd bugs than ever (even compared to my <gasp> Win7 setup). Cheetah was the last stable release imho).

i developed this same issue and did a log off and log on. that fixed it for me. funny how losing a feature that is so basic causes so much frustration.

I had this problem before. Then (I think) I restarted or something and it eventually started working. Problem began again a couple of days ago. After reading this tip, I logged out, logged back in, and hot corner for screen saver working again. Weird.

This solved my problem.

the same problem, It works fine until I upgraded to 10.7.4 these days.

any other help?

If you still have problems with Hot Corners not working, open Activity Monitor, select "mdworker" and quit process, then sit back and watch your Hot Corners work again.

Of course, this disables indexing for Spotlight, but once you do a Spotlight search, mdworker should start up again, but Hot Corners should also remain working.

I found this by pure chance. I always have Activity Monitor open and noticed that when I restart my machine, Hot Corners wouldn't work. So I looked through A.M. and noticed mdworker was using about 65% CPU, so i quit the process and viola, H.C. starts working immediately.

Hope this help everyone.

I also have the Hot Corners issue after using my Mac for a certain amount of time. It's clear that there is an OS bug triggered by some app behavior. I didn't want to log out to fix it, so I found that the easiest thing was to go to the Hot Corners setup in system preferences (Screen Saver > Hot Corners), switch one hot corner to something else, go back to the original, and hit ok. That will reset the Hot Corners which will work again. You can't just hit "OK" without changing anything, the OS will notice you didn't do anything.
