Cursor behaving erratically

Since a few days back I am having a issue with my cursor. The little arrow seems to have life of its own. The cursor jumps across de screens sometimes even performing clicks.
I have a Macbook Pro Retina with Maverick 10.9.1 installed.
How can I fix this issue?
Thank you,
D

Hello Diegooriani,
It sounds like you are getting some erratic cursor behaviour on your MacBook Pro. I recommend taking a look at the following information from the article named:
Portables and Magic Trackpad: Jumpy or erratic trackpad operation
http://support.apple.com/kb/ts1449
The Apple Magic Trackpad and built-in trackpads on Apple portable computers work on a principle called coupling capacitance. As your finger moves over the surface, the trackpad evaluates the change in capacitance between two layers of measurement electrodes built into the surface of the trackpad and translates that to cursor movement.
Verify only one part of your finger is touching the pad. You cannot use a pen or other object--the trackpad is designed to work only with your finger. Also confirm that you are not resting your wrist on or very close to the pad. The trackpad may interpret this as your finger touching it and make the cursor move in that direction. If you suspect either of these is causing the cursor's behavior, try raising your wrist in the air and touch the pad with only the tip of your finger. If the symptom goes away then, you know that one of the above is the cause, and you should adjust the position of your wrist or finger.
If you have sweaty hands or if moisture collects on the pad, this may also confuse the trackpad. Wiping off the trackpad with a cloth or tissue usually fixes this issue. If the issue goes away when a piece of paper is put between the finger and trackpad you may want to consider purchasing a Teflon applique to fit over the pad to prevent the moisture from having direct contact with the trackpad. Before installing the Teflon applique, confirm the trackpad is clean and dry. You can use a mild glass cleaner sprayed onto the cloth, not onto the trackpad itself to clean the trackpad.
Oil or lotion can also cause the same issue. Do not use hand lotion, or consider purchasing a Teflon pad to protect the trackpad. Before installing the Teflon pad, confirm the trackpad is clean and dry.
Jewelry may also cause interference. Try removing rings or bracelets and see whether the jumpy or erratic behavior disappears.
Apple has had some reports of this behavior related to power supplies made by a third party company. If you are using one of these power adapters, unplug it and try running from the Apple battery to see how the trackpad behaves. Also try using the Apple AC adapter instead of the third-party AC adapter. If the trackpad behaves normally while running from the Apple battery or adapter, there is most likely an issue with your third-party adapter.
Thank you for using Apple Support Communities.
Take care,
Sterling

  • Mac book pro trackpad and arrow keys behaving erratically

    Hi,
    Over the past few months I've noticed my track pad and arrow keys not working as they should and the problem has been getting worse until a few days ago the trackpad stopped working all together only for it to come back to life for a few hours then get worse again.
    Symptoms:
    The cursor keep sticking, you can't drag it smoothly across the screen.It'll suddenly jump to the top of the screen or you can only move it left and right not up and down.
    The main click stops working, it'll turn into a right click button so everytime you click I get a sub menu pop up.
    When I use the arrow keys to navigate a sub menu the highlight jumps around as if it's possesd.
    Sometimes I'm not touching anything and the cursor will move on it's own!?!
    I've tried resetting the PRAM but it doesn't work. Everytime I restart the mac book it works fine for a little while then gets worse again.
    Does anyone have a suggestion as to what's wrong with it?
    Thanks
    Chris

    The possible cause could be your List is too lengthy. What you can do is don't refresh the list when they press the key down but put a Button beside. Once they selected the value in the dropdown then hey click the Button to get whatever needed.

    Thanks - how would I do that?
    I am thinking that another possibility is the FirstOrDefault
    command that runs in the FocusItem method. I think that it is causing any arrow key (up/down) interaction to behave erratically, but I don't know what to use in its place.

    I just figured out the print quality issue for my wife with her new iMac and new printer.
    She replaced both at once and she couldn't understand why her Artisan 730 was lower quality then her Epson R280 when they had the same specs.
    Turns out the newer printer had the option to connect via wifi which we used during setup.
    The driver options are completely different depending on how you connect.
    Once I connected via USB the correct options were available and the print quality was better.
    Looking at the R2400 it dies not have wifi, but while researching the problem for my wife someone esle was having an issue updating to the latest printer driver.
    If you go into the print utility from the Printer and Scanner system preference and under the general tab you should have driver 5.5.
    One user had to delete the old printer driver before Software Update loaded the newer printer driver.

    On my MacBook Pro (w Snow Leopard) I always had to reconnect my wifi at home when it woke up. I upgraded my router from an old Netgear to a newer N D-Link and stopped having to do that.
    I would be surprised you would have that problem with an Airport Extreme, you might check to see if there is a firmware update for it.

  • Macbook Pro (mid 2012) inbuilt Track pad behaving erratically after fresh install of Yosemite 10.10.2

    I recently did a fresh install of the OS from online recovery. Mountain Lion was installed which I immediately upgraded to Yosemite 10.10.2. The trackpad started behaving erratically after two days. I seems that it started since I plugged one of my wifi router on the lan port. The trackpad is impossible to move as it seems to have a mind of its own. An external mouse connected works fine. Any help please !

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
    Isolating an issue by using another user account
    Try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

  • Scrubby sliders in the Lens Blur Filter in PS CC 2014 behaving erratically.

    The scrubby sliders in the Lens Blur Filter in PS CC 2014 are behaving erratically. In PS CC no problems. I may be mistaken, but I think I read somewhere that this filter only works on 8bit images.
    In PS CC it works on 16bit, and in PS CC 2014 (no third-party plugins) nothing works. Could this have something to do with the Graphic Card, or Cache Levels? All advice appreciated.

    Sorry, no solution to the problem, but a confirmation. I do have the same problem (Intuos Pro and Pen & Touch) showing the problem with ACR 8.5 and Photoshop (2014, CC and 6, these were updated with ACR 8.5) . No such problem before ACR 8.5 and no problem with LR 5.5 (also containing ACR 8.5).
    I hope there will be a solution from Adobe soon, since sems to be caused by the ACR update.
    Windows 8.1 in my case and latest Wacom Intuos driver installed.

  • How to fix: photos are behaving erratic or connected to each other

    Please help as I'm stymied! My Mac PS CS5.5, vs. 12.1 is behaving strange when more than one photo is open. I don't like tabs, so I've turned that off in preferences. I need to have several photos open at once, and like to spread them over the desktop to see them all at the same time. When I click on one photo, the others are behaving erratically: some are changing to show the same photo I clicked on or part of it. It's as if each window is connected. How do I turn that off or otherwise fix the problem, so that I can view each individual photo and even make changes to it, without it effecting the other open photos?
    I have already tried rebooting and deleting the settings file by booting PS while holding down the command, option, and shift buttons. And I checked for updates, but looks like I have the latest.
    Thx, Cindy

    Thanks for your answer. I tried fixing the following, but it didn't fix the problem.
    This is a brand new copy of Photoshop. Previous copies have worked fine on this computer. I just went to preferences/performance and changed the memory usage allowance up to 89%--think it was at 70%, and made an external drive with 1000GB extra space another scratch disk. Then re-launched PS. Problem is still there and happens even if I only have two photos open, plus no other software besides internet browser open.
    The mac is a fairly new tower with 6gb ram. Not sure how to find out which video card I have, but I did purchase the upgrade.
    Thoughts?

  • Imadmin domain purge behaving erratic

    We are facing problems while deleting a domain created through the delegated admin.
    it is saying container already exists while purging the domain through the command line,
    1.after deleting all the users and groups from that domain.
    2.after giving the -g0 option of imadmin domain purge
    3.after deleting o=internet suffix through the ldapdelet utility.
    really it is behaving erratically.We are unable to create the domain with the same name again.Hope everybody else also faced the same problem while going through the archives.Does somebody got any solution or this is a Bug from SUN, where they created like this????
    this is Quiet urgent.Please help immediately.

    Reply from Bruce Bergeron:
    Anyways, I assume you delete the users with "imadmin user
    delete" and then purge them with "imadmin user purge". Once
    this is done then you no longer have the users mailboxes or the
    users entries in ldap.
    After this you should be able to do "imadmin domain purge" ok.
    You said you then deleted o=internet. Why?
    o=internet contains the dc tree and should not have to be deleted.
    But if you assume you do not delete the o=intetnet dit then you
    should be able to recreate another domain with the same name.
    I tested this out on iMS 5.2 hf 1.21 with iDA 1.2 hf 1.3 and did not
    have a problem. iDA 1.2 hf 1.5 is out now.
    So iDA functions just fine. What versions of iMS and iDA are you
    using?

  • My iMac behaves erratically

    My iMac behaves erratically.  When I type i get disengaged from the window where I type. Then i hear a thud as if my mouse clicked somewhere out side the window i'm typing. I have to click back the window before i can continue typing.  I can only work around 15 minutes at a time then it would happen again.
    What's going on? It is annoying. and can't work much now.
    I need help.

    When you have the problem, note the exact time: hour, minute, second. 
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    The title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.
    Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
    Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
    Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
    Please don't indiscriminately dump thousands of lines from the log into this discussion.
    Please don't post screenshots of log messages—post the text.

  • AS3 Tweens behaving erratically

    Hi,
    I've put together this simple code for an SWF with three roll over images (called: Training, Resources and Contact).
    When I roll over Training I would like the symbol Training_txt to tween its alpha to 1 (from 0) and tween its y axis to 220 (from 83).
    When I roll out of Training I would like to run the two tweens in reverse.
    This works fine for each of the three roll over images, so long as each tween is allowed to fully execute before a new tween is started.
    The problem arises if i quickly move the mouse curser between the three roll over images before the previous tweens have finished executing.
    In this instance, the tweened objects start to behave erratically. They usually return to their original position as per the roll_out tween but then start jumping between y axis 200 and y axis 83 (without tweening - they just appear).
    I'm pretty flummoxed. I have declared an individual variable for each tween this has not solved the problem. Also, I am now declaring the vars outside of the functions.
    Any help very much appreciated!
    Code below -
    stop();
    import fl.transitions.Tween;
    import fl.transitions.easing.*;
    //TWEEN VARS
    var Training_txt_alpha:Tween;
    var Training_txt_y:Tween;
    var Training_txt_alpha1:Tween;
    var Training_txt_y1:Tween;
    var Resources_txt_alpha:Tween;
    var Resources_txt_y:Tween;
    var Resources_txt_alpha1:Tween;
    var Resources_txt_y1:Tween;
    var Contact_txt_alpha:Tween;
    var Contact_txt_y:Tween;
    var Contact_txt_alpha1:Tween;
    var Contact_txt_y1:Tween;
    //TRAINING BUTTON
    Training.addEventListener (MouseEvent.ROLL_OVER,Training_Over);
    function Training_Over(event:MouseEvent):void {
    Training_txt_alpha = new Tween(Training_txt,"alpha",Strong.easeOut,0,1,1.5,true);
    Training_txt_y = new Tween (Training_txt,"y",Strong.easeOut,Training_txt.y,220,2,true);
    Training.addEventListener (MouseEvent.ROLL_OUT,Training_Out);
    function Training_Out (event:MouseEvent):void{
    Training_txt_alpha1 = new Tween(Training_txt,"alpha",Strong.easeIn,1,0,0.5,true);
    Training_txt_y1 = new Tween (Training_txt,"y",Strong.easeOut,Training_txt.y,83,1.5,true);
    //RESOURCES BUTTON
    Resources.addEventListener (MouseEvent.ROLL_OVER,Resources_Over);
    function Resources_Over(event:MouseEvent):void {
    Resources_txt_alpha = new Tween(Resources_txt,"alpha",Strong.easeOut,0,1,1.5,true);
    Resources_txt_y = new Tween (Resources_txt,"y",Strong.easeOut,Resources_txt.y,220,2,true);
    Resources.addEventListener (MouseEvent.ROLL_OUT,Resources_Out);
    function Resources_Out (event:MouseEvent):void{
    Resources_txt_alpha1 = new Tween(Resources_txt,"alpha",Strong.easeIn,1,0,0.5,true);
    Resources_txt_y1 = new Tween (Resources_txt,"y",Strong.easeOut,Resources_txt.y,83,1.5,true);
    //CONTACT BUTTON
    Contact.addEventListener (MouseEvent.ROLL_OVER,Contact_Over);
    function Contact_Over(event:MouseEvent):void {
    Contact_txt_alpha = new Tween(Contact_txt,"alpha",Strong.easeOut,0,1,1.5,true);
    Contact_txt_y = new Tween (Contact_txt,"y",Strong.easeOut,Contact_txt.y,220,2,true);
    Contact.addEventListener (MouseEvent.ROLL_OUT,Contact_Out);
    function Contact_Out (event:MouseEvent):void{
    Contact_txt_alpha1 = new Tween(Contact_txt,"alpha",Strong.easeIn,1,0,0.5,true);
    Contact_txt_y1 = new Tween (Contact_txt,"y",Strong.easeOut,Contact_txt.y,83,1.5,true);

    OK, I've managed to solve this issue by using a work-around.
    I've downloaded and installed the Tweener class, and I have to say I will be using this for my tweens from now on. (Google 'Tweener').
    Thanks for looking!

  • IPad keyboard behaving erratically.

    I am using a new 10w USB charger for my iPad and when I try to use the touch keyboard it starts behaving erratically. I touch a letter and other letters appear and when I touch the delete button more letters appear? When i unplug it the keyboard is fine, is this a problem with the charger?

    I would try another charger now. Borrow one if you can or take your iPad and your charger to an Apple Store.
    If the iPad keyboard behaves erratically with another charger, it could be an issue with the iPad. If you switch chargers and the problem goes away, then I would assume that the charger is the culprit.
    Does this make sense to you?
    You can also try this and  see if it makes any difference. Do this while the iPad is not plugged in and charging. Reset the iPad.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
