Have to hold down mission control keys, when did this change?

I have my mission control keys (show windows in app, show all windows, and show desktop) set to use the F10, F9, and F11 keys without function keys.
Recently (as in five minutes ago) I noticed that the keys are no longer behaving like they used to. I now have to hold those keys to use any of those functions, basically making them useless because now my hand is occupied with that instead of using the trackpad.
Is there some update that happened that caused this change or is it just a product of some setting getting changed? I never noticed a setting for this in the System Preferences.
Computer: late 2008 unibody Macbook, 2.5 GHz, 4 GB RAM, running Yosemite 10.10.2.

Actually just solved my own problem.
Used killall Dock according to instructions here: https://discussions.apple.com/thread/3831445
and everything is now working as normal again.

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up.

Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up normally. Why do these key fonctions no longer work?

It could be your timing if on a bluetooth keyboard. I find it best to hit the keys as soon as i hear the chime, release and hit them again but this time holding them before the chime ends....like a fake pump in football.
But....you can always open up system preferences, startup disk, and select your bootable clone for booting. If it doesn't show up there, the Mac doesn't think it's bootable.

I copied our entire music folder from old PC on tovnew iMac, all our muisc is there, but not our individual libraries have gone. and holding down the alt key when opening iTunes, brings up no options to choose or create libarys, can i recover our liba

Hi
I copied our entire music folder from our old pc on to the new imac, and all the apps, music etc is there, but no individual libarys, we had 5 very different ones, when pressing and holding the alt key on opeing itunes, nothing happens it just opens into itunes, no option to choose or create a libary, what am i doing wrong?

Did you copy the entire iTunes folder, not just media? This includes the critical library.itl file.

Now you say you had 5 libraries. If you really mean that then you would have to have copied 5 different iTunes folders in their entirety, not just one folder. Anyway, something makes me feel you did not copy a whole iTunes folder and all its subfolders and files, you only copied the music.
On the starting with the option (alt) key held down I really don't know what to advise. It works for me hundreds of times and just about everybody else here. The only thing I can suggest is to hold the key down longer or perhaps start iTunes and then 1 second later hold down the key for a few seconds.

I tried holding down the shift key when opening Safari, and I still get the Apple homepage instead of the one I previously selected in Safari Preferences. I also set the two boxes above my selected homepage setting, with the same result.

I am also getting the "getadblock.com" every time I open Safari...it opens to that window and then downloads an adblock extension, which I do not want.

From your Safari menu bar click Safari > Preferencees then select the Extensions tab.
Uninstall the getadblock extension.
Quit and relaunch Safari to test.
If you launch Safari with the Shift key depressed and it doesn't open the General tab...
Might be corrupted Safari preferences ...
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.Safari.plist
Click Go then move the com.apple.Safari.plist file to the trash.
Quit and relaunch Safari to test.

My iPhone 4S has crashed 7 times. I hold down the home key and on button to reboot. I tried a restore but has crashed once since. Do I have a faulty phone ?

My new iPhone 4S has crashed 7 times ie the screen does not come back on when I press the home key. I hold down the home key and on button to reboot and it always comes back. I tried a restore but it has crashed once since. Is this right ? Do I have a faulty phone ? Any suggestions ?

Does the screen come back on if you press the sleep/power button?
Have you tried powering down (hold sleep/power button and swipe red slider) then power back up? Power cycling sometimes will clear problems.
If neither works, and you can get to an Apple store, have the genius bar folks try it out...they are very good about replacement if faulty.

I am unable to start up my iMac running on 10.4.11 - the startup disk is installed and will not start up eben when I hold down the "C" Key. I do get the apple, but then it disappears.

Query by serial number
Apple's warrenty database will identify the type of Mac you have. Your serial number is securely sent, but you get only the name of your machine.

This site provides more information, but lacks security.
"A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

Hey, My macbook is giving me a flashing question mark on startup. When I hold down the command key to get to system preferences it asks me for a firmware password, that I did not set! Any ideas on how to bipass this?

Hey, My mac book is giving me a flashing question mark on start up. When I hold down the command key to get to system preferences in order to help it find the system software it asks me for a firmware password, that I did not set! I also do not have the start up DVD/disk anymore. Any ideas on how to bypass this?

TS3048 I have just purchased a new apple cordless keyboard. The numeric line of keys along the top are not functioning as they should. For example I am unable to get a question mark or a forward slash. I have tried holding down both shift and alt keys.

I have just purchased a new apple cordless keyboard. The numeric line of keys along the top are not functioning as they should. For example I am unable to get a question mark or a forward slash. I have tried holding down both shift and alt keys.

Thanks for prompt response - I tried what you suggested but I'm afraid it has not helped. It seems as though the line of number keys along the top aren't actually doing what is printed on them. Some are OK, but the further towards the right hand side of the keyboard you go, the less predicatable it becomes. So whilst the second key from the left gives me 1 and ! when holding the shift key, by the time I get to the 6 when I press and hold shift I get ^ rather than & symbol which is what is actually printed on the key. The & symbol is actually on the next key along - and when I hit the key with 8 I get * rather than the ( which is printed on they key but actually located on the next key along. Things get even more muddled by the time I am over on the right hand side as rather than a question mark (I have had to type the word as I cannot find the symbol anywhere!) I get this _ and the other symbol marked on the key is a comma, but I get - instead. It is going to drive me mad if every time I want to type something it is a guessing game....! What do you suggest - question mark

HT1310 Even when holding down the option key during the restart, I can't get the flashing file icon to go away

I have tried numerous times to restart my macbook pro to get to the startup manager. And even when holding down the option key, it will just take me back to the flashing file with a question mark in it. If anyone can help, I'd sincerely appreciate it.

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

When holding down the 'command' key for a few seconds, the Universal Access panel appears. How can I stop this?

It is a panel that pops up and the heading on the panel is 'Universal Access', it is actually just an image of a panel, you can't access it. I have checked keyboard shortcuts and none of them are assigned to the command key only

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My iphone died and when I plugged it back in to charge it when it powered on the screen remained black. I can hear when I receive a text and a hear siri. I have tried holding down the sleep and home button

My iphone died & I plugged it back in to charge when it powered on the screen remained black. I can hear when I receive a text and siri. I have tried holding down the sleep and home button and restoring in itunes neither worked. The screen on the phone is cracked but has been working fine until now. Please help!!!

Here's how to perform the restore:
HT1414
If you can actually get to restore, maybe (I estimate a 0.01% chance) you'll be able to do a backup before the restore. Actually, from the symptoms you describe, I suspect a restore won't work either and you'll need to do a recovery.
Just in case, if you need to recover (restore fails), here's how. Note you may have to try to get into recovery mode more than once.
