Magic Mouse jumps all over screen

Have had it for about 6 months, brand new fresh batteries. It will randomly jump all over the screen when I am normally using the mouse. It just started to happen. I'm on a wired network and I have tried a white piece of paper and different surfaces. The mouse still randomly will jump all over the screen when I am moving it in normal use, it's as if it tracking ultra fast for a few seconds. And my keyboard will pause when I'm typing every few words as well.
Is this an interference issue?

FWIW
The issue seems to be related to using multiple monitors. Assuming one has two monitors the jumping mouse problem presents itself when the primary monitor is connected to a video card AND a secondary monitor is also connected to that same card, but NOT turned on. There seems to be some sort of interference b/w the Mac's bluetooth module and the mini-display adapter. Moving the secondary monitor to a second video card presents no problems with the jumping mouse in either the powered on or powered off mode.
Solution: Either turn on both (all) monitors or disconnect secondary monitors from the primary video card if planning to use only one monitor powered on at a time.

    *Magic Mouse is on Drugs*
    OK so first, let me say that generally speaking i love my mac. There was a time in the 90's when i was a big Apple fan, but after a few dumb@ss business decisions by Apple, i decided to convert to Windoze (and my entire company at that) So here we are a decade later; and I'm back on a mac again.
    Recently my MagicMouse started spazzing out. Randomly jumping to new points on the screen. At first it was mildly annoying. Now it's infuriating. I used Camtasia to record this behavior:
    http://www.youtube.com/watch?v=fX8ApUH6QOw
    I called Apple to discuss this. First, they said "they weren't aware of any issues" A quick google of "MagicMouse Jumps" returned hundreds upon hundreds of links (including this forum) describing the issue.
    Second, after assuring Apple this really was a problem, i got the ultimate insult. "If you would like to lodge a technical support ticket, we will need your credit card. This call will cost you $150.00."
    You see, I bought this thing four months ago. Apparently you only get a 90 day free call period. After that you're warranty is actually a cost per call scenario.....
    So -- While i love my mac, i'm of the distinct impression i've made the wrong choice. The only good news is I've now decided not to convert the rest of our 20 workstations in my business back to Mac....
    Apart from my b*tching, has anyone actually solved this problem that according Apple, doesn't exist?
    Oh by the way --- plugged in a USB laser mouse, problem does not occur with that device -- tried on all sorts of surfaces; mouse pads, no mouse pads, black paper, white paper, patterned, non patterned, special optical mouse pad for laser mice.... SAME results no matter what the surface is, and YES, i've also cleaned the optics with a lens cloth..... (And the battery is currently at 88%)

    Hello g:
    Welcome to Apple discussions.
    I suspect a faulty mouse. However, try two things first. Trash a preference file (com.apple.bluetooth.plist) and restart. Reset the PRAM:

    There is no Apple charge for a warranty issue and the mouse has a one year warranty. Call Applecare back (or take it to a store if they have one close to you). Unless I am badly mistaken, Apple will replace the mouse and pay for shipping both ways (I had one fail a couple of years ago myself). Do identify the call as a warranty issue.

  • My magic mouse keeps jumping all over the page

    Hi, my magic mouse keeps jumping all over the page and random apps keep appearing on my screen when I'm in facebook and it keeps sliding onto my dashboard screen.

    Thanks so much for replying Barry.  Did what you said but took me 6 attempts to be able to reply to you so unfortunately did not work.  Have to wait over a week to get into Apple store so I guess I've just got to wait.  This is my second magic mouse and its driving me crazy.  Touch pad also playing up but thanks for the advice and have a good day.

  • Does anyone know why my mouse cursor jumps all over the screen at times?

    Does anyone know why the mouse cursor jumps all over the screen at times, especially if I am playing solitare?  Is it Yahoo games or my Apple?

    Is this a Magic Mouse you're talking about?
    If so there's already discussions about this here and maybe related to it, here.  Also google something like "jumping magic mouse" and there's no end of discussions on this topic

  • Mouse is Jumping all over the screen...

    I have been having all kinds of problems with my mouse. The one on my computer will at times not respond to touch... I thought I had fixed that by wiping it down but it still isnt great...
    Then my mouse started having the cursor jumping all over the screen... I ended up going and buying a Magic Mouse as the guy at the store said my mouse was going bad... Well I have been great with the magic mouse for about 24 hours and now it is starting to do it again...
    Any ideas of what I should do?

  • How can i stop Pages and Numbers JUMPING ALL OVER THE SCREEN. MAKING ME SEASICK! PLEASE HELP

    how can i stop Pages and Numbers  screen JUMPING ALL OVER the place when i just touch my mouse. i have tried and tried to change the mouse settings - but it is the software. especially Numbers. you can't even see what the page size is until you print. i am so SEASICK! PLEASE HELP.

    Thanks for the trouble to reply. this problem only happens with Pages and Numbers for me. i have done all the tricks like restarting. the main problem is that the working space is not 'stable' - it has no 'ends' even on full screen. in Numbers - UNLESS I SET IT TO 25% VIEW (which is way too small) - the actual total 'work space' is way off the grid - so every time i move the mouse the table i am working on zooms off to left or right, at the slightest touch. i have set my mouse to no gestures!
    the thing is this did not happen before the latest upgrades.
    but thanks anyway. SG.
    if you are a techy person - i have another prob. in Mail i am unable to set the SORT / VIEW messages to BY DATE.
    (it used to be ok, at one time, too). now it continually reverts to BY SUBJECT oh so annoying !
    restarting etc does not change it. resetting preferences does not change it.
    maybe i need a new Mac ?
    mine is a 27-inch, Mid 2011. running latest.

  • Satellite C600 - Cursor jumping all over the screen

    I was just issued the Satellite C600 and I cannot type without my curser jumping all over the screen. I've followed the advice from other threads with no success. "FN+F9" does not disable the touchpad, and there is no touchpad tab under Mouse Properties. In fact, when I search the whole computer for "touchpad" there is no response.
    Please advise!

    Hello
    Why you try to disable the touchpad?
    On Satellite C series there is a BIOS update that will solve this cursor jumping issue. There are already a lot of threads here in forum:

    Help! My Mouse pad is not working properly. The arrow cannot be controlled, it just keeps jumping all over the page. How can I stop this?

    There are several possible causes for this issue. Please take each of the following steps that you haven't already tried until it's resolved. Some may not apply in your case.
    1. Follow the instructions in this support article, and also this one, if applicable. A damaged or defective AC adapter could be the cause, even if it's the right kind.
    2. Press down all four corners of the trackpad at once and release. If there's any effect, it's likely to be temporary, and in that case the unit must be serviced or replaced.
    3. Open the Bluetooth preference pane in System Preferences and delete all pointing devices other than the trackpad, if applicable. Disconnect any USB pointing devices. By a "pointing device," I mean a peripheral that moves the cursor, such as a trackpad, mouse, trackball, or graphics tablet. A plain keyboard is not a pointing device.
    4. Start up in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you restart as usual, stop here and post your results. Do the same if you can't start in safe mode. If there was no difference in safe mode, go on to the next step.
    5. Reset the System Management Controller.
    6. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
    7. A swollen battery in a portable computer can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced without delay.
    8. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built-in trackpad of a MacBook to  behave erratically. If you're using such an adapter, disconnect it and test.
    9. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
    10. If none of the above applies, or if you have another reason to think that your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
    11. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.
