MacBook Display - Text Glows or Fades When Scrolling with Two Fingers

I am currently using an early 2008 MacBook Black, OS X 10.5.5, 2.4GHz Penryn, 4GB RAM (CAS 4), 250 GB HDD. I recently came into an Apple Store for a Genius Bar appointment because of a problem with the screen. When I use two finger scrolling and view text on a white background, the text appears to glow (especially blue text) or fade (black fades to an almost imperceptible gray. This behavior appears in Apple's Safari, Pages, Numbers; as well as, Safari. I have not tested beyond this yet.
The Genius at the store had no answer for this behavior and the other early 2008 MacBooks in the Apple Store (Walden Galleria, Buffalo, NY 14225) also exhibit this behavior. The Genius admitted this was annoying when viewing text and it appears to be a driver or OS problem because this behavior is also exhibited on the late 2008 MacBooks and MacBook Pros.
Suggestions?

It's a characteristic of LCD response time. There is nothing to be done about it except maybe experiment with different colors of text or backgrounds. That's not always practical, I know. Basically, we all have to live with it.

  • Clicking noise when scrolling with 2 fingers on new MBP?

    Hi Everyone,
    Just got a Penryn 2.6 MBP 17in, love the machine, it is pretty much perfect.
    I have just noticed that sometimes on graphically intensive web pages if I scroll using two fingers there is a very slight clicking noise coming from under the G and H keys. It kind of also seems to come and go, it is not an always thing. Is this normal?
    It also seems to do it more when on magsafe power rather than on battery... I am thinking this is just the graphics card making noise, but I was curious if others have experienced this?
    Thanks!

    yeah for me its around the delete button though. How come nobody is answering these clicking questions?

  • After EFI firmware update the scrolling with two fingers doesn't work inside the browsers (both safari and chrome)

    I've got a new MacBook Pro Retina from october 2013 13" (8 gb Ram and 256 gb SSD).
    I had the "freezing" issue that was solved with the firmware EDI update.
    But after this update i have now another problem: often during web browsing the scroll with 2 fingers up and down the page stops working (but the trackpad is ok for everything else and if i go in other programs the scroll works as usual). The only solution is to restart the browser but the problem happens again and again.
    Both on Chrome and Safari. Especially on Safari everything freeze if i try to scroll on the right to go back to the previous page.
    Does anybody else have this issue?

  • Using Firefox 8.0 on a MacBook Pro I can no longer enlarge the text on web pages by sliding apart two fingers. Why?

    I just downloaded Firefox 8.0.1. I have a MacBook Pro running Mac OS X 10.5.8. In the past, I could easily enlarge text on a web page by sliding two fingers apart, or likewise, make the text smaller by pinching the fingers together. I can no longer do this with the latest version of Firefox. If I run Safari instead, I can still use this feature of the Mac. Is there a setting I need to change? Or is it a glitch in the new version of Firefox?

    Some gestures have been removed in Firefox 4+ versions.
    You can restore the zoom feature by changing the values of the related prefs on the <b>about:config</b> page.
    * browser.gesture.pinch.in -> <b>cmd_fullZoomReduce</b>
    * browser.gesture.pinch.in.shift -> <b>cmd_fullZoomReset</b>
    * browser.gesture.pinch.out -> <b>cmd_fullZoomEnlarge</b>
    * browser.gesture.pinch.out.shift -> <b>cmd_fullZoomReset</b>
    * browser.gesture.pinch.latched -> <b>false</b>
    To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br />
    If you see a warning then you can confirm that you want to access that page.<br />
    *Use the Filter bar at to top of the about:config page to locate a preference more easily.
    *Preferences that have been modified show as bold (user set).
    *Preferences can be reset to the default via the right-click context menu if they are user set
    *Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)

    So which touchpad do you really have? Elan or Synaptic?

    It's a Magic Mouse question. I have set this up in Preferences by ticking Swipe between pages with one finger and also Swipe between full-screen apps with two fingers,  however when I try to do the latter, the 2 finger swipe will take me from the app that I am on to the dashboard only and not to my other open apps.
    I also find that Smart zoom only works with some apps, for instance not with Word docs or email.
    How can I correct this please?

    Just figured out it also does not work with the Mail app.

  • PDF forms have problems displaying text and only appears when the field is selected

    Hello,
    I created some pdf forms to distribute to the company clients. But we are having some people complaining about the text visibility. When they have work in team, the pdf that they receive from a third person often appears unfill or without text, the text is only visible when the field is selected. I need to find a solution for this because our company products are base on this forms.
    If there is any addition information that I should add to understand what is happening and how to fix it, I'll be happy to write it.
    In the company, we all have mac and the forms where created innitially in Adobe acrobat 9 pro, but we have now Adobe acropabt XI pro.
    The users have both Mac and Windows systems.
    Thank you,

    This is usually caused by the form being filled-in and saved by a Mac user who is using the Preview application to view the PDF. More information is here: http://kb2.adobe.com/community/publishing/885/cpsid_88564.html
    It is a good idea to inform your users that Adobe Reader (or Acrobat) should be used to work with the forms.

  • Webpages enlarge when scrolling with mouse

    Sometimes when I am scrolling up or down a page in Firefox, the page will stop scrolling and the page will instead start enlarging or shrinking, depending on whether I am scrolling up or down. I am not touching the keyboard when this happens and definitely did not hit the Control button first. It just randomly starts happening, usually when scrolling through a lengthy page, such as my Facebook newsfeed. This has been happening for several months. What can I do to stop it? It's really annoying!

    Make sure that you do not press the Ctrl key.
    You can set the <b>mousewheel.withcontrolkey.action</b> pref to 0 to perform a scroll.
    To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br />
    If you see a warning then you can confirm that you want to access that page.<br />
    You can use the Filter bar at to top of the about:config page to locate a pref more easily.

  • Interactive Form jumps back to the cursor when scrolling with the mouse

    In an interactive form over multiple pages, the user should enter some fields and will then scroll down - usually with the mouse's scrollwheel. As long as the cursor is in an active field, adobe reader keeps jumping back to the place the cursor is active... So it is not possible to scroll down.
    Scrolling down by sidebar works fine.
    As a workaround, I can place the cursor outside of any entry field (just by klicking any text within the form) and scrolling down works fine again.
    I guess this is a "feature" and not a bug - but it is driving our users crazy!
    Any suggestions or ideas about how I could get scrolling to work will be highly appreciated.

    I didn't find any such behavior, and I never heard about it earlier.
    Some how I feel this is not a feature nor bug in adobe, its something with your form. may be there is a set focus cdoe somewhere or so.
    can you send me the form to test it in my local pc ...?

  • How to display an double type variable's value with two decimals?

    for exmple, what I do is:
    double a = 1.5;
    system.out.println(a);
    I see 1.5 in the screen, however, I wanna display 1.50. how to do that?
    I know how to round an double value, say, 1.555 to 1.56, but I can't find how to display a double value from one decimal to two decimal, any help will be very appreciate!

    for exmple, what I do is:
    double a = 1.5;
    system.out.println(a);
    I see 1.5 in the screen, however, I wanna display
    1.50. how to do that?
    you could convert the double to a string and then append a zero to the end
    String str = Double.toString(a);
    str += "0";

  • New MBP 17-inch anti-glare display creates a moire pattern when scrolling

    This is kind of hard to explain: The color on the display is fine when a page is stationary, but when I scroll vertically, the blues (especially light blues) and reds get a strange tint to them and create an effect that's hard on the eyes. The graphics don't break up or anything but the color vibrates. It's very uncomfortable to watch. I've owned and used many Powerbooks and Macbooks over the years and this is the first one that's had this problem. It's like a moire pattern, or something. Very odd.
    Is anyone else noticing this on the anti-glare display? I'd like to know before I go ahead and return this MBP.
    Thanks

    Sure. No two sets of circumstances are exactly the same, so no one else will have experienced exactly what you've experienced, including the prior replacement of an earlier MBP model for repeated display problems that you haven't specified. AppleCare will weigh all the circumstances of your current issue on their own merits and make a decision about what to do without reference to other people's problems. No one here knows what that decision will be, whether you believe me or not. Call AppleCare.

  • Display text in navigation bar when user is logged in

    Hi all,
    I'm (still ) on Apex 4.2.6.
    Currently, I have in my page templates, the following snippet:
          <div class="logoBar">
              <img src="#IMAGE_PREFIX#themes/theme_125/images/logo_.png" />
              <h1><a href="#HOME_LINK#" id="uLogo">#LOGO#</a></h1>
            <div class="userBlock">
              <span>Username: &APP_USER.</span>
              #NAVIGATION_BAR#
            </div>
          </div>
    I have the requirement to display both the username (APP_USER) and the company the user works for (Application item AI_COMPANY), only when the user is logged in. When the user isn't logged in; instead of those items, I have to show a login link. Well, I know how to only show a link to the login page, when the user isn't authenticated, using the navigation bar. Currently, when a user isn't authenticated; the page shows: Username: nobody. That's because it is in my page template. How can I only show the username when the user is logged in? And show the company name only then?
    My first thought was to add an item in the navigation bar. But those items shows up as links. Is there a way to add a navigation bar item, and let it display as text? Sure, I could write a dynamic action on page 0 to remove the link, but I'm searching for a nicer/better sollution.
    I apreciate your help!

    Hi tomvdduin,
    you can show company name which is already in your Application item(AI_COMPANY)  by modifying the page template mentioned above.
    <div class="logoBar">
      <img src="#IMAGE_PREFIX#themes/theme_125/images/logo_.png" />
        <h1><a href="#HOME_LINK#" id="uLogo">#LOGO#</a></h1>
      <div class="userBlock">
        <span>Username: &APP_USER.(&AI_COMPANY.)</span>
        #NAVIGATION_BAR#
      </div>
    </div>
    I have included company inside ( ), you can change how you want to show.
    for example
    <span>Username: &APP_USER.</span><span>Company: &APP_COMPANY.</span>
    Hope this helps you,
    Regards,
    Jitendra
