  • I am trying to edit my website using the copy and paste function and am getting an error message that says my browser will not allow this function.. what do I do? thanks!

    I am trying to do a simple copy and paste function while editing my website and I am getting an error message that says that my browser will not allow this function.. how can I override this?
    thanks

    You need to set Copy'n'Paste security policies for that domain in Firefox.
    AllowClipboard Helper will help you do that. <br />

    I got it out!
    Here is how.
    None of the Apple-suggested ways worked. However, before totally giving up I started Roxio Popcorn and pressed the big eject button on it. It came out effortlessly!
    So, I thought "Weird..."
    I put the CD back in and reproduced my original problem. I got it out just as easily using Roxio Popcorn Eject feature.
    So, I then thought "Maybe it is the disk?" There is nothing wrong with the disk as far as I can tell. It is perfectly round, has a smooth label-side surface. It is not even a label, it is a standard software install disk you buy in stores.
    I inserted a different disk. The mini mounted it, I browsed it, and then ejected it by dragging it to trash. Worked fine.
    I tried a few other disks.
    The drive seems to work fine.
    Maybe that CD is cursed, I dunno. I tried that disk in my PowerBook and it works fine there.
    Who knows ?
    I am still backing up my hard drive as I type this message in case I need to take it to the store.

  • I bought the Keynote app for my MacBook, but when I open the application and try to install it, I get an error message saying that the application will not work with my MacBook. What gives? And, can I please request a refund? ($19.99 = a week's groceries)

    I bought the Keynote app for my MacBook, but when I open the application and try to install it, I get an error message saying that the application will not work with my MacBook. What gives? And, can I please request a refund? ($19.99 = a week's groceries).
    Thank you for your help! - I did try looking for all available specs about Keynote on the Apple iTunes website, and found nothing that could help me. HELP!

    1
    Close all iWork applications
    2
    Uninstall Keynote; this must be done with an application remover tool to delete the installation properly. Appcleaner is known to work correctly for this purpose, it is free and can be downloaded from here: Appcleaner Download
    3
    empty the trash
    4
    shutdown the Mac and restart. After the start up chime, hold down the shift key until the apple logo appears
    let the Mac complete the start up procedure completely, it will take longer than usual as the hard drive is being repaired
    5
    Reinstall Keynote by logging into the Mac App Store using download / install

  • How to stop an error message that pops up every time I open Safari. It reads...Safari 5.1 (v6534.50) has not been tested with the plugin PithHelmet .As a precaution, it has not been loaded. Please contact the plugin developer.

    How do I stop this error message from popping up every time I start up Safari ?
    Error message reads...
    Safari 5.1 (v6534.50) has not been tested with the plugin Pithhelmet 3.0b6 (v 3006)
    As a precaution, it has not been loaded. Please contact the plugin developer.
    I have removed every trace of Pithhelmet, (via spotlight)
    Trashed the preferences for Safari, restarted computer to no avail.
    It just  keeps keepin on.
    Thanks

    In the past I was able to bypass the message by editing the Info.plist file and updating the MaxBundleVersion variable, but not so this time around. As of today the developer seems to indicate there's no immediate fix becuase of how Safari 5.1 handles multiprocess page rendering. Probably best to stay tuned to Mike's website for now.

  • "Sync encountered an error while syncing: Unknown error. SYnc will automatiall retry this action" - this error message keeps popping up

    "Sync encountered''' an error while syncing: Unknown error. Sync will automatically retry this action" - this error message keeps popping up whenever I am on my email accounts. I hit the "Sync Now" icon, but it comes back after a while.

    Note: I just tried deleting and re-creating my Sync account, reinstalling firefox, and deleting places.sqlite, with no success. And "Eooro" from the title is supposed to be "Error".

  • Firefox "starts" but browser will not open on desktop

    When I click to open Firefox min Windows 7, the program loads, i.e., I can see the window on the Aero Bar, but the browser will not open on my desktop. I have redone my profile and that seems to solve the problem for a while, but then the same problem reoccurs. This happened with four different profiles. When I do get the browser open on the desktop, I find a load of error messages in the error console.

    Hello Joseph.
    You may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal? [http://support.mozilla.com/en-US/kb/Safe+Mode Safe mode] will do it easy, if you can't hope Firefox.

  • My Reminders app will not open. When I try to open it, quits and gives me an error message: "Reminders quit unexpectedly while using the CalDAV plug-in." My Reminders is synced with my iPod touch, and it is fine on that. How do I fix it?

    Also, the Calendar is loading very very slowly, and sometimes it quits and gives me the same error message as above.

    The problem has been fixed with the most recent OS X software update.

  • HT1925 After failed update of itunes yesterday, now will not run with error message "MSVCR80.dll can't be found, APSDaemon.exe not running".  Windows 7.

    After failed update of itunes yesterday, now will not run with error message "MSVCR80.dll not found" APSDaemon.exe will not run.  itunes will not now run.

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support (if this won't uninstall move on to the next item)
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
    Please note:
    Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

    I have bought several tv seasons from the itunes store. Recently some episodes will not sync with my ipad. The error message is that the file "could not be read or written". Previous episodes of the same series synced successfully. Also while watching the same episode on my laptop (Mac Book Pro) it freezes.

    I had this same message appear today when i was putting new music on my ipod touch 4th gen. The only difference is that I wasnt using an external drive. I was using the one on my computer. This is the first time i have had this problem
