I can't seem to figure this one out...

 

I have always enjoyed being able to take pictures of individual windows displayed on my iMac.  I've always used the keyboard shortcuts to do so, but now when I type "Command+Shift+4+SpaceBar" the entire screen is highlighted, as if I just pressed "Command+Shift+4".   A little while ago, I lost that ability and I'm not sure if i've inadvertently disabled the feature some how or if it's a code corruption or if this is the result of an Apple update.

 

I haven't seen any other questions about this, so, is anyone else having this problem or have I just doofed and somehow disabled this?


iMac, OS X Mountain Lion (10.8.4)

    First thing to try is restarting the computer. Second thing to try is restarting into Safe Mode then restarting normally.

    No joy.  The screen capture works just as expected in Safe Mode.  Upon restarting and business as usual, whenever I try to capture a picture of an individual window... the entire screen is highlighted.

     

    I have double checked the settings regarding Keyboard Shortcuts in the System Preferences, something which I never bother modifying, everything is in order.

     

    Thank you for the suggestions, Kappy!

    Something may be corrupted somewhere. So, next step:

     

    Create a new user account with admin status. Log out of your account and log into the new one. Is the problem fixed? If so, then the issue is in your Home folder. If it is not fixed, then the issue is in a system file. In this case reinstall OS X:

     

    Reinstalling Lion/Mountain Lion Without Erasing the 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 the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.

     

    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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.

     

    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

    Please read this whole message before doing anything.
      
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
       
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.

     

    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.

     

    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.

     

    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.

     

    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.

     

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.

     

    Step 1

     

    Triple-click the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
     
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
        
    Step 2

     

    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook 2> /dev/null; } | open -f -a TextEdit
     
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.

     

    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.

     

    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
     
    Step 4
    ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
      
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.

     

    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
     
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.

     

    You can then quit Terminal.

    This is the kind of "diggin'-in-diagnostics" I would love to be more capable of doing.  It was a lot of fun!

    Here are the results of the diagnostic:

     

    Step 1:

     

    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit

     

     

    Nothing printed to screen.

     

    Step 2:

     

    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook 2> /dev/null; } | open -f -a TextEdit

    ---------------------------------------------------

     

    This, once again was very, very awesome to me.  As a result of this testing, I was able to begin the usual "suspect elimination process" - not to mention discovering a few pieces of software that still lingers on my system from software tha I have since "uninstalled".

     

    I'm happy to report that to source of the problem was the that little app I downloaded quite sometime ago to reduce the brightness of my screen while working late at night.  I never had an issue with it before so I'm guessing in the last update, something went wrong.  The app is the "Brightness Slider".  As soon as I quit that app, my ablility to screen capture individual windows was restored.

     

    You are awesome Linc Davis!  Thank you so much for this help.  If you don't mind me asking...  Is there a specific book or other resource that you could recommend to me wherein I couldget a stronger understanding/grasp on this level of troubleshooting Mac OS X?

     

    Thank you so very much again - This was a lot of fun!

    Thanks for the kind words. I don't know of a good book on OS X troubleshooting. That's not to say that none exists, but if it does, I don't know about it.
