Hi All


I am having a issue with my Macbook which is irritating the **** out of me now and I need some advice or help.


Every so often my mouse moves on its own and the screen moves, not completely just so it is half on one window and half on another. Then I also every so often get the Dictionary / Wikiedia pop up (when the word goes yellow and the pop up appears). The problem is that is does this on its own, and it makes no difference if I am using the tracker pad or magic mouse.


Any ideas what i can do???


Thanks all in advance!

    Did anyone help you with this? I am having this exact problem and I cannot seem to figure out how to fix it. No one at apple knows either.


    My desktop also keeps enlarging, at its own will, and open windows are zooming off the page. . .


    MacBook Pro, OS X 10.8.2


    Please help!

    This is a really easy fix:


    System Preferences > Trackpad > Point & Click > Uncheck "Look Up" > Voila. Whoever you spoke to at Apple was an untrained, underqualified individual, kind of like the ones I always get to talk to.

    I know this has been dormant awhile, but this all just started happening with me as well.  It does not happen when I'm plugged into my external display -- mouse works just fine, no strange display jumps or zooms.  However, as soon as I unplug and use my normal display, I have the same exact issues noted above.  I did follow your advice and that took care of the dictionary issue, but everything else is still happening...any ideas would be greatly appreciated!

    I had this same problem. If my mouse pointer hovered over any word in any window the dictionary would pop up. Or the mouse pointer would shift to the right or left a few centimetres, or the launchpad would appear as I was clicking on something...




    I downloaded AVG Anti virus and let it run for a few hours. I had remembered using the free AVG on windows 15 or so years ago when I was still a win32 developer...


    It found a trojan horse Generic13_c.APBT in

    ~/Library/Containers/com.apple.mail/Data/Library/Mail\ Downloads/4796DD75-31D2-47A9-B051-E3E479BFC433/swearing_email.doc


    I had never opened this email in Apple mail as Google had already labeled it as spam and I had deleted it. At least I don't think I opened the email...


    Anyway, AVG quarantined the file and the problems seem to have gone away..


    I hope it has anyway...
