  • How to remove the icons from games to screen all applications

    I uninstalled all my new laptop Win 8 games, but there is always a 'Games' section on the screen all applications containing icons for 'All Casual Games', 'All lovers of games', 'All family games', "All games for children" and "all MMO games. Right click on these icons and choose "Uninstall" takes me to the Panel configuration "Programs and features", but the applications are not listed.

    Any thoughts on how to remove these unnecessary icons from the screen of all the Apps?

    Thank you!

    I found a solution using registry edit. This tutorial was written with Windows 7 in mind, but also works with Windows 8.

  • Cannot scroll with the scroll on my mouse button in some Applications

    How do I can't scroll with the scroll on my mouse button in some applications? Happen for example when I tried to scroll my Lotus Notes e-mail messages. I was not able to scroll using the button on my mouse! Very annoying!

    Hi X04p2n! I had the same problem! I was not able to scroll with the scroll thing (dunno what it's called) in note either. Just, I went on the site and downloaded the correct drivers for my mouse and it works since.

  • Cannot scroll with my mouse screens.

    I just downloaded Firefox on my computer last week because we'll go to a new software and they recommended we use Firefox. I am not able to use my mouse to scroll to the top and bottom of pages. I have to use the side scroll bar which is not really effective. I just want to be able to use my mouse to get better. I use Windows 7 on an ordinary PC. I probably have a setting that should be changed, but I can't. I already went in the options and checked the AutoScroll and tried other settings as well. Help!
    Thank you!!
    Carolyn

    Does the mouse work outside of Firefox?
    It does not work on all sites?

    Start Firefox in Safe Mode {web link}
    While you are in safe mode;

    Type of topic: preferences< enter > in the address bar

    Select Advanced > General.
    Find and stop using hardware acceleration.

    Search web sites secure. Are there problems?

    Then restart.

  • Cannot download an update of Firefox 8.0.1 suggested by your request - computer cycles (all other applications are closed), can I do that?

    Download is not downloading - may have attempt half dozen times over the past weeks...

    If he has problems with the update or the permissions then simpler is to download the full version and trash the version currently installed to do a clean install of the new version.

    Download a new copy of the Firefox program and save the file on the desktop disk image (dmg)

    • Trash the present application Firefox to do a clean (re-) install
    • Install the new version you downloaded

    Your profile data is stored in the Firefox profile folder, so you will not lose your bookmarks and other personal data if you uninstall and (re) install Firefox.

  • cannot scroll when copying

    I can't scroll when copying of text on a web page. When my selection reaches the bottom of the page with my mouse it just will not go further. This problem does not occur in any other application, or IE 8.

    I have not had this problem myself, because I have the bar of the Add - it open all the time. I saw this question be posted here by other users of recalledl a few times. Guess I remembered that cause a little bass-ackwards.

    Sounds like it may be this Bug, which is linked to a full screen or maximized window.

    https://Bugzilla.Mozilla.org/show_bug.cgi?id=644621

    Has been fixed, bur, it has been corrected for Firefox 8.0 and I cannot understand if it's supposed to be in Firefox 9.0 or not.

    https://Bugzilla.Mozilla.org/show_bug.cgi?id=675865

    Shows like "Assigned" and not "resolved".

    Hello:

    Can please tell me how to adjust the size of the forms or Web sites when they do not fit the screen and does not allow me to finish the forms by scrolling. Sometimes, in the middle of downloading applications or programs, blocks education not loading small enough for me to click on things (the boxes are too big for the screen).

    Can you please tell me how to solve this problem.

    Sue

    You want to change the size of the browser window?
    If you use Internet Explorer, you should try to press Fn + 1 or Fn + 2
    Also you could do a zoom in and zoom out in the view that is located in the Menu bar
