I'm use two screens, Firefox 4 is not displaying correctlying on my second screen. How do I fix this? (I have Windows 7, 64 bit, and using an external video card)

It only happens on the screen I'm using the external video card. I'm assuming its a bug.

I think this is related to other posts, the solution at the moment seems to be to disable hard acceleration.

  • Using Windows 7, i-tunes will not connect to i-tunes store.  How do I fix this?

    Using my desktop with Windows 7, my iTunes will not connect to the iTuens store.  All other functions of iTunes works great.  I have all other programs that require internet working just fine..ie browsers (IE, FireFox or Chrome, and all email services) and all work normal. 
    I updated iTunes to current version as of today April 6, 2012 and now it does not work going to the iTunes Store.
    I have about 6-8 different Apple devices that use this iTunes, but right now, none of these are connected with my iTunes, as I was just going in to do some music shopping first before connecting any of them to my PC. 
    How do I fix this?
    Thanks in advance for any and all helpful information!
    Angie

    Close your iTunes,
    Go to command Prompt -
    (Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
    (Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
    In the "Command Prompt" screen, type in
    netsh winsock reset
    Hit "ENTER" key
    Restart your computer.
    If you do get a prompt after restart windows to remap LSP, just click NO.
    Now launch your iTunes and see if it is working now.
    If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

  • TS1702 After installing the new software to my iPhone 4S , my dream zoo either will not start or when it does it has a blank screen that has a few icons on it that wont work. How can I fix this is it possible to go back and reinstall the older software ?

    After installing the new software to my iPhone 4S , my dream zoo either will not start or when it does it has a blank screen that has a few icons on it that wont work. How can I fix this is it possible to go back and reinstall the older software ?

    Unfortunately I tried that and it didn't work. Thanks for the help though. I tried to uninstall and it said I couldn't because the file is corrupt or something, but I think I finally got it uninstalled and/or deleted or whatever, but now I try to reinstall/download it again from the beginning and I can't. No matter what I do I can not get Firefox working again. No matter how many times I try to redownload it. Any other suggestions?

  • Firefox math symbols not displaying correctly

    Firefox math symbols not displaying correctly and special characters not display correctly
    Example: triangle symbol display "D" , but other browser is displaying fine.
    Please give me a solution.
    Thanks & Regards
    Ajay Kumar

    This page uses the Symbol font to display the triangles.
    <pre><nowiki>font-size:12.0pt;font-family:Symbol;mso-fareast-font-family:"Times New Roman";mso-bidi-font-family:"Times New Roman";color:black</nowiki></pre>
    It works for me on Linux, but probably not on Windows.<br />
    Websites shouldn't be using this Symbol font, but use the Unicode replacements instead: Δ (&amp;#916; &amp;Delta;).

    DVD drives read the bottom of the disk, not the top. Smooth out the paper & try again.

  • TS3274 i dropped my ipad and now i have a "green screen" how do i fix this?

    i dropped my ipad and now i have a "green screen" how do i fix this?

    If it's an iPad 2, it's old enough to be out of warranty. Courcoul's suggestion to trade it in for a new one is ok if you are in the market. If not and you want to take a risk - and possibly a big one at that - others have reported a pretty extreme solution to this problem. Slap it on the back.
    I know, I know. It's sounds crazy, but there are several threads here claiming it works.
    Here is just one of them. You can do a search to find others.
