Observing many computers causes erratic mouse movements on client macs

hi!
I administer a mac lab and when I select all the computers in the class to observe, the student mouses move erraticly.
do you guys ever encounter this problem ?
thanks for your help.
macs are imacs.

Got it !
While waiting for Apple to come up with a bug fix (if they ever do, since it probably affects only french users.)
You can always copy the RFBMultiObserveWindow.nib folder from the English.lproj to the French.lproj... (After having made a copy of the original NIB folder first of course...) And this fixes that...
I have noticed no localization aberration while doing this.
Good luck !

  • Erratic mouse movement

    When using my USB IR mouse or a magic mouse the cursor suddenly jumps about the screen often to a "Hot corner" which turns the display off. I do not recall that this occurred before I loaded Bootcamp and Windows XP Pro.
    Any help out there?

    I've seen this happen for two reasons.
    1.) My imac is about to overheat and crash. The pointer seems to jump around the edges of the screen and on rare occasion reservse themselves. UP=DOWN LEFT=RIGHT..etc.
    2.) The mouse picked up a hair and the IR light is bouncing off of it and causing erratic movement. (More often the case)
    Hopefully 2, but be mindful of 1. I would be curious if you have iStat and notice any difference in operating temperature during these times.

  • Erratic Mouse Movements

    Since upgrading to lion, I have noticed my mouse has began moving randomly to different corners of the screen. Is anyone else experiencing this, or do you have a fix?
    Any contribution would be greatly appreciated.
    Nathan

    I have had the same prob on my MacBook Pro.  Tackpad mouse as well as a wired and wireless mouse. Eratic, gets stuck, jumps or no response.
    I am very very sorry that I downloaded Lion.  Snow Leopard worked very well but read that Lion was SOOOOOO much better.
    This reminds me of dealing with Windows operating systems when there were first released!  I have actually started using my PC Laptop again.

  • Erratic Mouse and Keyboard issues...with weird console log...

    Hello All,
    I recently installed Snow Leopard on my 2x2.8 Quad Core Mac Pro following a boot drive melt down. Apple replaced the drive via Apple Care and I re-installed all my apps. The only additional item of note is I have Lycom SATA four port card that required a driver update.
    Since setting up this machine with the new OS I am having massive issues with keyboard lag, erratic mouse movement and intermittent freezing.
    I've run tech tools deluxe and everything passes with that app. I cant find the original install disks so running AHT on this machine isn't going to happen.
    I've tried with and without the driver and the issue seems to still be there.
    On a whim I opened console and I am seeing this message hundreds and hundreds of times over...
    8/8/10 2:21:11 PM com.apple.launchd[1] (org.xinetd.xinetd[2652]) Exited with exit code: 1

    Jstys92,
    Heat?  Motherboard?  Sounds like hardware since it's across Operating systems...
    If you have a warranty, this is the time to call HP.
    HP Product Warranty Check
    Contact HP - Worldwide
    Contact HP - USA
    If not, I still think you have a HW issue.  It is relatively consistant, too.  Like something is breaking down - physically.  Not a disk - BIOS... notherboard... something that holds everything together.
    Computers are not supposed to warm up and then start doing whatever they want.
    We do not live it in that world, at least not yet.
    ===========================================================================
    You could run some Diagnostics.  The UEFI Diagnostics, if you don't already have them on your system, are very good and provide a decent "human interface".

  • Why does the mouse move erratically in PSE 13?

    why does the mouse move erratically in PSE 13?

    I'm getting the same thing.  This is the second major problem I've had with Adobe Photoshop Elements 13.  They just corrected the first problem where there was a "default printer" error coming up when printing.  This is ridiculous.
    My mouse freezes erratically when I click on the main drop down menu.  It works okay when editing photos.  The mouse just acts erratically on the Main drop down menus.  My suspicion is the new update that fixed the default printer error has caused this issue.  I am really hoping someone from Adobe is viewing this forum.  It took 3 months for Adobe to fix the printer issue.  I hope this isn't the case with this issue.

  • How can I correct Unstable, erratic mouse cursor movement

    I currently have a dual boot setup with Windows 7 Pro 64 and XUbuntu 64 bit XFCE desktop. On random occasions, the mouse pointer will begin to float and or will not stay positioned on the spot selected.  This occurs with or without an external mouse attached.  The track pointer will not control the mouse and neither the left nor right keys just below the keyboard function.  The drifting will stop sometimes when the center key at the bottom of the keyboard is pressed. The touchpad and its keys seem to work correctly.  I have turned off both of these in the BIOS and have not had any problems.  It seems to me that the problem may be with the keyboard. Any body have any experience with this sort of problem?  

    Hi
    Thanks for your post
    To  help you further on this issue please share more details
    1. erratic mouse cursor movement  is happening  in win 7 or ubuntu
    2.  please share the touchpad driver version   &  bios version
    Cheers!!!

  • Mouse movements cause F10, F11 and F12 automatically.

    Unusual problem...
    When i move my mouse in a particular way . e.g diagonally towards the spotlight ( top right corner) this has the same effect as pressing F11- i.e the windows shoot off towards the top of the screen and i ma left with my desktop. Infact other mouse movements can cause the same result as widgets appearing .
    can anyone help? I have a macbook. Although i have Leopard this problem was still in Tiger.
    Thanks in advance.

    Sounds like "hot corners"..
    Try going to System preferences > Desktop & Screen Saver > Screen saver.
    You will see a "Hot corners" button at the bottom where you can adjust what the mouse does as it hits the corner of the screen.
    Before spaces I used this shortcut a lot to reveal the desktop:)

  • Jumpy mouse movements on Asus netbook

    Just installed FF 4.0 and using it on an Asus netbook 1101HA. Whenever I use the mouse on a website, the mouse moves erratically, noticeably erratic. This problem is not apparent in any other app. (I'm using the mouse pad and not an external mouse.)

    Hi Rod,
    we are working on this with our team, and here are some interesting things we found out:
    We uploaded a non-scorm course  on Moodle and it works smoothly. In Captivate every page will  communicate with the LMS for bookmarking and reporting. Maybe for that  reason the animations are not smooth. With this observation we are  trying to play around with the layers in Captivate to see if it brings  any difference.
    Here is the link to the non-scorm course: http://mytechschool.com/moodle/file.php/101/Multi%20Color%20Pen%20-%20v1.38.htm
    The communication that occurs on each slide is causing the jumpy mouse /  slow mouse movements.  Is it possible to fix it by modifying / adding javascript  into the HTML wrapper so the SCORM package didn't send the results until  the end of the assessment?
    How can we do this?
    Here is the moodle post where they provided javascript  code to accomplish this task.  Unfortunately, when this code is used, it  doesn't record the results in the gradebook.  We could use help from  the Adobe community to modify this code so it records the results in the  gradebook while avoiding a jumpy mouse.
    http://moodle.org/mod/forum/discuss.php?d=79349#p804524\
    TIA.

  • Right-click down mouse-move gives no onMouseMove event in Safari on  Mac

    I am trying to detect on-mouse-event in JavaScript, when the mouse is moving while the right-button is down in Safari on Mac. But it seems the onmousemove event is not fired.
    Note: I am able to detect the mouse move combined with right mouse down on windows event FF on Mac.

    I figured that the form wasn't public, but I asked just in case.
    Yahoo in general is not very Mac-friendly, but still, what you are experiencing is not normal and must be very frustrating, especially when someone is looking over your shoulder (isn't that when computers act up the most?).
    Because the form works in Internet Explorer, the problem is not a general OS X problem, but if this is the only form that you have problems with in Safari, then my first guess is that the page the form is on is not written to the accepted standards for writing web pages. Safari is one of the least forgiving when it comes to bad or incorrect coding of web pages.
    If you have this problem on all or most forms, but things continue to work in Internet Explorer, then one thing I would try is to delete Safari's Preference file. I have seen all sorts of seemingly unrelated but Safari-specific problems arise when this file gets corrupted (which isn't often). The file is named com.apple.Safari.plist. Not all problems are caused by a bad preference file, so this procedure may not work.
    First quit Safari. You can copy the file name (com.apple.Safari.plist), click on the Spotlight icon in the upper right of your screen, and paste it in the search box. One entry should be found. If you click on "Show All" in the results window, a larger Spotlight window will appear and you can drag com.apple.Safari.plist to the Trash from that window. You will loose any changes you have made in Safari's Preferences and a new one will be created when you restart Safari.
    You might want to consider Firefox as an alternate browser. Internet Explorer is now longer being updated or developed and is now behind the times and renders many pages poorly.

  • Mouse moves on its own

    hey,
    does anyone have the same problem?
    my mouse on the screen moves on its own and presses random buttons:( so annoying
    I haven't had this computer even a year and its giving me a problem.
    I use logitec wireless mouse. is there anything i need to set up in the preferences?
    thank you

    There are several possible causes for this issue. Take each of the following steps until it's resolved.
    1. Follow the instructions in this support article.
    2. Open the Bluetooth preference pane in System Preferences and check for unknown or forgotten input devices. Disconnect any USB input devices that you aren't using.
    3. Boot 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 reboot as usual, stop here and post your results. If you can't boot in safe mode, do the same. If you booted in safe mode and there was no change, go on to the next step.
    4. Reset the System Management Controller.
    5. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
    6. A swollen battery in a MacBook Pro or Air 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.
    7. 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.
    8. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
    9. If none of the above applies, or if you have another reason to think 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.
    10. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • Mouse moves strangely

    My mouse (the arrow) got uncontrollable. I tried replacing battery and some other things but basically I lost control and even writing this is a pain

    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 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. If your model has an infrared receiver for use with an Apple Remote, disable it.
    5. 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.
    6. Reset the System Management Controller.
    7. If you're using a Bluetooth trackpad or mouse, investigate potential sources of interference, including USB 3 devices.
    8. 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.
    9. A defective peripheral device or a damaged cable can cause the built-in trackpad of a MacBook to behave erratically. If you're using any wired peripherals, disconnect them one at a time and test.
    10. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
    11. 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.
    12. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

  • Computer not responding to mouse movement

    For the past week my magic mouse has been getting stuck or will move crazy slow when I'm using it and is slow to respond. It will randomly loose connection. I have changed the batteries and chnages mouse pads. I switched to my husband's magic mouse and it does the same thing on my computer so now I'm thinking it's my imac's problem and not the mouse? Sometimes it works perfect but after an hour it starts acting up again. Right now I'm just using a logitech mouse and it's working fine. Thoughts?
    Thanks in advance!

    Check for signal interference
        Wireless networks that operate on 2.4GHz may cause interference.
        Move cordless phone base stations, microwave ovens, and other 2.4GHz electrical devices away from the Mac if you suspect interference.
        Keep wireless devices within 10 meters (33 feet) of the Mac.
        Avoid putting metal objects between the device and the Mac.

  • My macbook pro is frozen, the mouse moves, but it will not click.  I have restarted and it is still the same... Can anyone help me ?

    my macbook pro is frozen, the mouse moves, but it will not click.  I have restarted and it is still the same... Can anyone help me ?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain models. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
