The cursor keeps moving, even when I'm not touching my mouse. I use a Logictech wheel mouse. It's hard to use the computer with such an unstable cursor. Any ideas?

MacBook Pro 2.6 GHz, 2GB RAM, Mac OS X (10.6.4)

    You're probably resting your hand on the trackpad. It's not disabled even with a mouse.

    Not touching anything the cursor moves. And while I'm on a website the page changes. Could this be a virus?

    There are no viruses on Macs.

    I still think you're touching the pad, but it could be anything from a corrupted mouse driver to an old bad mouse to something we haven't diagnosed.

    The cursor moves even when the mouse is disconnected and I'm not touching the computer. And pages change by themselves. The computer seems unstable.

    Have the same issue - cursor movement random with no device input or touch
    occurs in safe mode
    occurs after cleaning the trackpad

    a restart and usb device disconnect seems to stop the moving/jumping cursor

    can anyone reproduce - a jumping or random moving cursor by placing a fan near the macbook and blowing air over the trackpad?

    OSX 10.6.4
    macbook pro i7 15

    Interesting. Will try.

    I disconnected USB devices and restarted computer. Cursor still unstable. Maybe the machine needs to be repaired.

    It's unlikely a repair
    finding and identifying variables involved in random cursor movement - more productive

    How about trying this for random cursor movement
    on Macbook Pro i7 OSX 10.6.4

    1.
    reset SMC
    shut down
    plug in power
    hold down keys (left) Shift + control + option + power button
    release all
    restart



    2.
    restart then hold keys
    Command & Option + P+R reset PRAM & NVRAM

    this looks to be a likely solution
    (fan + wind + touch pad thing not)

    What is SMC?

    Same issue.

    I also have a fan that I use to blow air over the keyboard to keep it cool and get the jumping cursor. But I get the jumping cursor even when I turn the fan off.

    Still now solutions? I have a Kensington Expert trackball (K64325 model) with a MacBook Pro.

    This is driving me crazy.

    Still no one has discovered a solution?

    OK
    I believe i discovered at least one cause for the jumping random cursor movement.
    seems to be a software conflict (in my case)

    on a macbook pro 15 i7 OSX 6.4
    also use Kensignton trackball & WACOM tablet - NOT THE Cause of cursor movement
    nor blowing fan

    is bluetooth + software conflict

    a restart in SAFE mode ( hold shift key down + restart) should be able to observe if a software conflict - no random cursor movement - leave bluetooth on -

    Bluetooth + "WITCH" software (if using the WITCH switcher disable in preference pane)
    Solved the cursor problem for me

    Tried safe mode and resetting PRAM. Cursor movement stops then restarts. Seems to happen when I rest my left hand on the notebook while typing even though my hand doesn't touch the Trackpad. Maybe it's a software issue, e.g., OS update.

    I have had this similar jumping cursor issue.

    Issue occurrs when using either the mouse or the trackpad for pointing or selecting items on screen (ie same behaviour: the cursor either temporarily freezes or jumps to a different part of the screen, making accurate point and selection a nightmare).

    A few users mentioned devices (ie mouse) should be disconnected and reconnected, so I tested the following:
    1. my external 24" monitor connected but POWERED OFF - cursor issue
    2. my external 24" monitor connected but POWERED ON - no issue
    3. disconnect the powered OFF monitor - no issue

    As I only use the external monitor occassionally it also explains why the cursor issue has been intermittent. For now the work around is obvious but something evidently is not right with the external monitor connection/port.

    This only started happening in the last 2-3 weeks. Will update if any changes noted.
