Why is Firefox preventing Windows 7 from shutting down? I must force quit.

When I try to shut down Win7 (Home Premium) , Firefox hangs and must be manually force quit. If I close Firefox before shudown, there is no issue. There are no warnings when I open or close Firefox (3.6.8).

I have the same problem. I run 3 different PCs, all with Windows 7 x64, FireFox 9 in all cases and on all systems this problem happens. When I shutdown Windows while FF is still running, FireFox will hang up and it has to be force closed. When I exit FF before shutting windows down, no problems occur.

  • Disable "this program is preventing windows from shutting down"

    Hi
    My application, that I am porting from Embedded Standard (XP) to WES7 uses the standard power on/off switch of a PC to power on/off. I intercept the FormClosing event and cancel the OS from shutting down. I then display a dialog box in my program asking
    if the user wants to shut down the system. If they respond yes then I shutdown the system from within my code. This works fine on XP, but with WES7 you get the screen telling you "this program is preventing windows from shutting down". I then have
    to press 'Cancel' to get to my application as before. Does anyone know of a way to prevent WES7 from showing this message and allowing my program to block shutdown quietly.
    Many thanks

    pennbank is correct that holding the power button will stop the computer.  But it stops *all* processes mid-step, which can leave some of OSX in an incorrect state because of pending internal file updates that were killed.  I do not like to use that method if anything else will make it respond.  For example, once the computer was not responding when I was using a BT trackpad.  I eventually removed the batteries from the trackpad to force it dead, and the release of the BT channel freed the MBP.

  • How do I prevent windows from shutting down ITUNES with a Data Protection Execution error when trying to sync with my Iphone 4S in a 32 bit windows environment?

    I first was not able to install ITunes 10.5.  Apple upgrade installer caused a data protection execution error and windows reverted the process back to the original software.  I then removed ITunes through the control panel ap.  I removed Bonjour and quicktime.  I could not use the windows uninstaller to remove the apple upgrade installer and had to find a fix it program on the microsoft web site to fully remove this program.  After doing this, I was able to load and install itunes 10.5.  However, now when I try to sync my new 4S phone, the sync only goes to the 2nd or 3rd step before eliciting a DPE error and causing itunes to shut down.  I tried making a new user profile.  Opened I tunes in the new profile and began to search for music on my computer.  The program again elicited a DPE error.  I looked to see if quicken was still on the computer and maybe causing a hangup, but it is no longer installed.  Ok, I am at wits end and have spent much too much time on this issue.  Please help.

    I was able to finally stop ITunes from crashing after many days of searching n restarting my computer many times.
    a) First I went to this site ->http://forums.techarena.in/guides-tutorials/1119812.htm that showed me how to disable DPE. Please make sure that u have good virus...etc.. protection first before doing this. I have Avast Internet Security. RESTART UR COMPUTER..
    b) I then uninstall ITunes by following this site ->http://support.apple.com/kb/ht1923      RESTART UR COMPUTER..
    c) I then downloaded a beta version of ITunes. I happen to download beta 7 before the final of 10.5 version came out. Installed it. After installing I click on it n it said somewhere along the line of "this ITune ver. expired" I checked in my Programs n Features n notice that QuickTime was installed w that beta version.   
    d) Go online n download the final version of ITunes ->http://www.apple.com/itunes/download/ ...... After u finish dling install that. After that's done connect your IPod, IPhone...etc... n click on ITunes, it should sync all the way.
    I was finally able to sync all thru the steps insteading of it crashing on me midway. Hopefully this will work for you. Good luck !

  • AcroRd32.exe: This program is preventing Windows from shutting down.

    Hello,
    when i try to shut down i have to kill the process first/Force the shutdown.

    Is there a solution available?
    Thanks!

  • Preparing move to trash preventing me from shutting down

    A window showing the message "Preparing to move to trash" runs constantly and is preventing me from shutting down my computer. The window is titled "Trash" and has a horizontal blue & white striped moving cylinder (like a sideways barber pole) and indicates there is 1 item to delete. I tried to force close but that does not work. Looking for a way to close this window. Thanks.

    Hi jholla, and a warm welcome to the forums!
    You're likely to have to Power down with the power switch, then do some repairs...
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
    The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
    Some people get away without Repairing Permissions for years, some for only days.
    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
    The combo update for PowerPC-based Macs...
    http://www.apple.com/support/downloads/macosx10411comboupdateppc.html
    The combo update for Intel-based Macs...
    http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
    Repair Permissions after re-install, then reboot again.
    If all the above do not resolve the problem, then it's time for an Archive & Install, which gives you a new OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...

  • Mail keeps preventing me from shutting down

    This has happened a few time now that when I try to shut down or restart my computer it doesn't untill I force quit mail even though it doesn't freeze or crash it just keeps saying mail is preventing my computer from shutting down. When I ok that though mail doesn't show it's window when I click it in the dock and thats when I have to force quit it.
    I do keep mail as a seperate desktop or "space" but it works fine till I have to shut down. This doesn't happen all the time but its done it now and again, has this happened to anyone else?

    Yes, this has been going on for a while. If you open Window > Activity' from the Mail menu bar, you should see that what's happening is that its trying to close the connection with your webmail server.
    Sometimes it happens to me, sometimes it doesn't. I suspect its just down to the internet connection.

  • Imac won't shut down - asked to force quit programs

    Hi Everyone,
    I've had my iMac for about a year now. No issues until now. Recently when I try to shut down from the apple menu it doesn't do anything for a minute or so, then I get a pop up that asks to to quit a certain program or programs that are open. It asks me to force quit them. It seems to be anything I had open, like mail or safari. This never happened before. It would always just shut down. So, if I go back and quit all the open programs I think are open, then try to shut down, it still doesn't shut down. I then have to manually hold the power button to force it to shut down. When I quit all the programs, I don't get an task bar at the top to pick the apple icon to then shut down as well. Can anyone help with why this might be doing this recently and how to fix it? No new programs of any kind have been installed recently. I'm not real good at computers but I know something is not right with this now as it always would just shut down from the apple menu with no issues.
    Thanks in advance for your help!

  • Macbook won't shut down unless i force quit!

But then refused to start up! 1st time it's done this!! it took over two hours to convince it to start!!! Any thoughts would be massively appreciated ..... apple care run out and ZERO funds to have fixed !!! : (( v sad as i love my mac and can't do without it!!!

    Exactly what did you do to run Disk Utility and exactly what happened up to the freeze?
    I called some place to ask for advice and they said it could be my logic board???
    That's an easy answer to give but not necessarily the correct one.
    If you have the system restore disc that came with your Mac, boot with that disc in the Mac while holding down the "D" key. That will invoke hardware diagnostics. Run those several times to investigate the possibility that your Mac has a hardware flaw.

  • Mail repeatedly prevents Macbook from shutting down

    When I attempt to shut down my computer, after the countdown, a dialog box saying that my Macbook can't shut down due to Mail not quitting pops up. I force quit Mail and then it shuts down correctly, but this has been an ongoing thing. It originated maybe 2 weeks ago. Prior to that, I never had any problems with Mail preventing shutdown. Any ideas?

    Bryan, RC-R, TBrad, Barry, Eric;
    I am new posting here, and only a 10 month Mac User.   I have had a similar problem with Mail.   I did try opening the activity window to examine for any processes working, during any Laptop shutdown actions.   The "Activity" screen for MAIL was empty.
    I did find a thread (but I very helpful thread here) which worked and solved the issue.   I cannot find that thread again.   But what I did was follow the instructions, via FINDER, to GO TO a specific folder from the the MAIL.  It was called Cache.db   The forum instructions to drop it into the TRASH.   That particular folder on my laptop was about 6.7 Megabytes in size.   I dropped it into the TRASH.    Then I went through the LOG out process.  MAIL still required a forced shutdown.    Upon restarting the Laptop,  I tested MAIL for OPENING and CLOSING and this corrected the problem..
    Search the MAIL threads here,  you will find the this solution, with better detail than I can provide.  What I can say is that it worked for me.    And there were 3 to 4 other replys on that thread with the same good outcome.   This fix was easy and simple, and produced no interruption in my use of MAIL.   No need to enter re-enter any information of any kind, nothing is lost other than eliminating the "hang up" of the MAIL application.   I am running Maverics 10.9.2
    Best of luck to all of you.

  • I am trying to shut down my MacBook Pro but mail is preventing it from shutting down and it will not allow me to quit mail

    Does anyone know of a way to force quit Mail.  It is preventing me from restarting or shutting down my MacBook Pro running Maverick iOS 10.9.
    Thanks.

    itsKeef,
    You're having the same problem? Do you ALWAYS have to Force Quit Mail or will it sometimes just Quite when you select Quit? Which model MacBook Pro do you have (e.g., "15-inch Late 2011"), which version of OS X are you running and which version of Mail do you have?

  • TimeMachine prevents iMac from shutting down?

    I am a proud owner of the new 27" iMac with a new 1TB Time Machine. No problem there.
    However, when the Time Machine is backing up and I choose shut down (from the shut down menu) TM should stop and resume the interrupted backup next time I start up. Instead shut down proceeds normally until I get the blank screen with a small spinning black wheel (the last thing we see before a Mac turns itself off), and then it stays there - forever. Twice I came in the next morning and found the spinning wheel still going on. Other times I give up after 2-3 minutes and force a shut down. Shut down is problem free if I have stopped the back up to the Time Capsule prior to shut down.
    I have a slow internet connection and so I am wondering if that is the problem. Any ideas?

The delay is in Finder; I have not noticed delays within CS4 applications; nevertheless it rather slows down the workflow.
    I don't recall seeing that reported very often. When OSX puts up that save window, it has to list all the places you could possibly put something, and checking the network for the status of all such locations, while a backup is busily using the WIFI connection, takes longer.
    Try the things in #D2 of Time Machine - Troubleshooting.
    I have experimented with putting the iMac to sleep instead of shutting down, and this appears to work without problems.
    Great!

  • The mail app on my macbook pro is preventing me from shutting down, how do I fix this?

    The mail app on my computer is open but nothing is displayed on the screen. When I go to shut down a small message appears saying "unable to shut down as mail is still open". However, when I try to close the mail app it won't let me. What do I do?
    Thanks

    pennbank is correct that holding the power button will stop the computer.  But it stops *all* processes mid-step, which can leave some of OSX in an incorrect state because of pending internal file updates that were killed.  I do not like to use that method if anything else will make it respond.  For example, once the computer was not responding when I was using a BT trackpad.  I eventually removed the batteries from the trackpad to force it dead, and the release of the BT channel freed the MBP.

  • Mail app preventing mac from shutting down

    Trying to shut down mac book pro. Just imported all mail into mail app. Error message stating mail canceled shut down and to quit mail and try again. Did that, same error message

    Was your import completed? Do you have any other ongoing Mail activity? Check what the Mail process is doing:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    I would suggest as a start to move the com.apple.mail cache folder to the Trash, but do not Empty it. You will find it in one of the Cache folders in the /Library/ or /Home/Library/ folder unless you are running Mavericks.
