Mouse pointer goes to corner

I've been having a problem with my USB apple mouse (not mighty) on my imac G5 where suddenly the pointer goes to one corner (not specific one) without doing anything in particular. I don't think is the surface, I've changed and made some test with different ones, Any ideas?

My cheapo basic Microsoft optical mouse did that on one of my Macs. Strangely, it did not do it on my other Mac, so I just switched the mice. It might just be a mechanical defect. Also, the older clear top USB Apple "Pro" mouse had a design weakness where the cable at the mouse body would start to fray inside from repeated bending. There might be a short circuit developing because of this issue. I fixed one of those using the instructions on the web. If you think that might be the problem (and it gets worse), take a look...

  • Mouse pointer goes for itself

    My mouse pointer will jump quickly to the corners of the display while working with it. I've made different adjustments to the mouse tracking speed to no evail. Does anyone have the answer? It is quite annoying when in the middle of a graphics project.

    Hello,
    While the problem is more related to the perception of the optics in the mouse, than it is the mouse pad; a good mouse pad will make a difference.
    I have been using Optical mice for a couple of years now. And, the problem you point out has been consistent in all of them (various brands and models).
    Apple's optical mice are very sensitive about changes in the texture of the surface they are on. Patterns need to be very consistent, and very regular.
    The problem has to do with how sensitive your optical mouse is to changes in the surface that you are moving over. You will have your best results on Mouse Pads designed for optical mice.
    I finally found a mouse pad that minimized the problem for me.
    I was in Office Depot in the Seattle, Washington area, and noticed these excellent pads.
    I am very particular about the Pads. I will not use a cloth pad, or anything with any thickness to it at all.
    I don't like cloth pads because they get disgusting and nasty. Furthermore, I don't like pads that are thicker than a single sheet of fine paper. I find thick pads uncomfortable.
    So, I had been specifically looking for a good mouse pad that was not only suitable for optical mice, but also extremely thin. I used to have a thin one, but it wasn't good for optical setups.
    So, with all the above in mind, I set out looking for a new mouse pad for my optical mice.
    I looked around my local area, and couldn't find anything suitable for optical mice that was also extremely thin.
    So, while in Washington, I stopped by every store we passed that might have something suitable. Finally, Office Depot had it.
    They are round mouse pads, as thin (or thinner) than a sheet of paper), and have a pattern that optical mice like.
    They are called "WOW!PAD"
    The company that makes them is at:
    http://www.microthin.com
    My pad is "Dots 007" if you look at the pictures on the page at:
    http://www.microthin.com/prod_wowpaddesigns.htm
    You can read more about the pads by going to the following page, and selecting the different options in the selection box:
    http://www.microthin.com/prod_wowpad.htm
    I've found that it almost completely eliminated the pointer problems on my Microsoft Mouse, and 100% eliminated the problems on both my Apple Pro mouse and Mighty Mouse.
    My Apple mice don't jump around at all now. So, give that a try. I think you'll be pleasantly surprised.
    I hope this helps.

  • Mouse pointer going crazy

    My mouse pointer started doing weird things about a month ago and I hope someone can help.
    When I am browsing the web using Camino 2.0.3, the pointer seems to take on a life of its own at times and just moves to another part of the screen by itself. I've replaced the mouse I was using (the one with the scrolling ball) with the stock mouse and it still does it.
    Any ideas?

    Hi macjack, thanks for the response.
    I haven't tried another browser lately, but will do that. I should add that I had been using Camino for a while before the problem with the pointer started, so am a little doubtful that it's the browser. But...I could be wrong.
    I'll give another browser a try and see how it goes.

  • MBP behaving weird. Often mouse pointer goes erratic, then freezes...

    After half a year usage, my MBP starts to behave strangely. The problem starts with mouse pointer gets erratic. That means, it does not respond to my finger stroke on the trackpad. When it does it moves really fast. Then the computer freezes and I have to force shut down. I still can't quite find the pattern of it. I often run cocktail clean up. I use disk warrior the graph the state of the hard drive and it shows 36% if items are out of order. Is this the main cause? I will try to rebuild directory with diskwarrior later. I only have about 8-9 gb of free space left on a 120gb HDD. I gave 32gb to windows partition. Would it be the culprit of the problem?
    Could someone help? I really want my MBP back to the way it used to be - STABLE, FAST.

    Could you explain more about what DW says about 36% of items out of order? And what does DU say about your SMART status? And what brand of hard drive do you have? I am beginning to wonder about the state of your hard drive. If you have directory problems that Disk Warrior cannot fix, then maybe that is why you can't create a bootable clone. And maybe there are problems with your hard drive that go beyond just the directory.
    There is a little program cqlled S.M.A.R.T. Utility you can download and run several times for free that can tell you quite a bit about your hard drive if your drive is supported:
    http://www.versiontracker.com/dyn/moreinfo/macosx/32454
    You might also try running the Apple Hardware Test and see if anything shows up in the form of an error code.
    I assume that you have verified both permissions and the drive and have attempted to repair both. And that there is something that cannot be repaired. Is this right or have I misunderstood you?
    If your problems are being caused by your hard drive going south, then that could happen with any computer, including a PC. I have heard about some Seagate models failing prematurely. Also some unfavorable comments about Hitachi drives. Check out what you can about the health of your hard drive and post back before going to the trouble of a format and reinstall.
    Good luck!

  • Mouse pointer jumps to corner of secondary screen

    We just upgraded to a new server running the latest Solaris with Sun VDI 3.1 which includes Sun Ray Server Software 4.2. I have multihead enabled and have 3 stations with dual-monitors/Sun Rays. On the second monitor, especially when dragging or scrolling, the mouse pointer jumps to the top-left of the screen. All three of us are experiencing this. Two have xinerama extension enabled, one does not have it enabled and says he's seeing the same behavior with the mouse. We have mix of Sun Ray 1G's and 2's, and one I'm using is a 170. I did not experience this with our old server running SRSS 3.1. Anything I can do to fix this problem? I appreciate any help.

The best case for this patch that has reached this stage of the process might be two or three weeks. The worst case could be a month or two.
    Alternatively, is there a hotfix available as many of our users are having difficulty at the moment.If you have a support contract then you can open and escalate a support call against the bug. After the escalation has been filed you can request an "IDR" ("Interim/Diagnostic Relief"), which is essentially an early build of the patch that contains the intended fix for that bug. The IDR will not have been tested by QA so there's some risk involved in taking it. This is one reason why we don't routinely publish IDRs. You have to decide whether that risk is outweighed by the pain the bug is causing.

  • [SOLVED]How to show desktop by moving mouse pointer to a corner?

    I did it in ubuntu with a easy compiz-fusion config tool. But I totally forget the name of the tool.
    Now I want to do it in archlinux, but I cannot find how.
    Last edited by danielking (2008-06-29 14:54:30)

    I think it is Fade to Desktop in the options for it you can set what ever corner or side of the screen that you want. Mine is set for the top left corner (KDE). I could be wrong though I am at work right now and my memory sucks.

  • Windows 8 Freezes after last "Lenovo Settings Update" anytime the pointer goes to a corner

    After the most recent "Lenovo Settings Update", my Windows 8 freezes for a few minutes (minimum of two) anytime the pointer hits one of the hot corners.  The system also freezes for a couple of minutes or less when certain apps are started or the mouse clicks on certain apps.  This is a repeatable error.  I can restore the system to the setpoint previous to the "Lenovo Settings Update" and everything works fine.  re-Install the update and the problem comes back.  The system also freezes for 5-10 seconds when an e-mail message comes in and the notification appears.  Also happens under other different circumstances but the worst is when the mouse pointer goes to any "Hot Corner".  I can reset the system to the last restore point and have everything work fine but anytime I go to "Lenovo Settings", it forces the update which then creates this problem.
    Has anyone else seen this issue?  I have all the updates for Windows 8 and Lenovo installed including all new Bios updates that are published.  The model is  a Lenovo ThinkPad Edge S320u (otherwise known as the "Twist". The error is repeatable in all screen modes, tablet modes and multiple monitor modes.
    For now I will go back to the latest restore point but would like to see the issue resolved.
    Thanks.
    Bob

    I had the exact same issue with the same computer (Thinkpad Twist)! Am very happy to have come accross this page through a web search.
    After installing some updates through Lenovo Update App (because of a message that critical updates are available on the Lenovo Support App from Startscreen), my whole system would freeze for about two minutes when moving the cursor over any corner. This is very troublesome not only because it effectively disables the Windows 8 "hot corners" (which I didn't use much anyway, preferring to launch the tasks thus accessible differently), but mostly because it is necessary at times to access the corners, notably to close any document, webpage or other instance of any program that was open in full screen (which usually all of my docs/programs are, considering the Twist's small screensize...).
    Afer reading rbagnall's post I first tried uninstalling updates through the Lenovo Update center. But there, once installed, updates don't seem to be removable. Why Lenovo? You can look at the list of installed updates but not make any change. Now I have followed rbagnall's advice and restored my computer with a restore point, sufficiently far back, as I didn't know exactly which update caused this. It worked! Not exactly pleasant, because I had to reinstall some programs and change some settings again, but the problem got resolved.
    I went further and tried to see which update causes this by installing them one by one and seeing when the problem appears. The culprit seems to be "Display Mode Orientation Update for Windows 8". One needs to install the "Lenovo Power Management Driver" with it (which is actually listed under optional updates, whereas the Display Mode update is shown as a critical one, but the former is selected automatically when the later is chosen, and one cannot unselect it, a message appears then that it is necessary for the other update). So it could be that one as well (haven't checked whether installing it without the Display Mode update creates the same problem). In any case, once these are installed, the problem appears.
    I have now restored my PC again to the restore point, and haven't installed any Lenovo update, not even the other critical one, as I don't know what it's for (Critical patch to fix TVSU UTS issue - I haven't had this issue, and any web entries on this I found dated back to 2009). In the optional updates there is also a BIOS update, which I had installed previously, but I don't know what it's for either. If there is anything terribly useful in either (or other optional updates), please tell me.
    For now I have uninstalled the Lenovo Support Startscreen App (which seems to be more annoying than helpful), and will refrain from updating any Lenovo drivers from now, which seems to do more harm than good (everything was working fine before the update)...

  • When mouse hits upple left corner of screen, windows disappear

    The upper lefthand corner on my Macbook Pro is hot. When the mouse pointer hits the corner, the active windows on my screen collapse off the desktop. When I hit the same corner again, the windows reappear. Is there a setting in System Preferences which will remove this function? Thanks

    Open the Exposé and Spaces pane of System Preferences, click on the Exposé tab, and change the entry in the upper left menu to a dash.

    Laptop with  do random zoom in fuctions while in safari.
    Its at the point where im ready to take it in to Apple or Geek squad but i know it will cost me an arm and a leg if they solve the issue.
    The only time i can normaly use my laptop is if i keep it shut down and keep it off for extended perioud of time
    If any one have any sudjestions plz help

    First few times I used the Magic Mouse it worked fine. Now I have the same problem I did with old wireless mouse -- pointer goes to middle of screen and then drops to bottom. Keyboard recognizes mouse, and MM will open icons along bottom of screen, but will not function above about 1/2" of bottom of screen. Can't scroll up to close open programs, can't scroll to the left to Finder, etc. Have replaced batteries a couple of times, have rebooted (including powering completly off). No luck. Have an iMac, working in Snow Leopard.

  • Mouser pointer changes on unit label

    Hi
    I noticed that whenever the mouse pointer goes over a unit label it changes its icon from the default to an entry field icon (icon # 3), although you cannot enter or write anything in the unit label field.  Furthermore if you click inside the field the flashing line appears but, as intended, does not allow the user to write anything inside.
    Is there a reason why this is happening or left this way?  More importantly how can i make sure that the cursor does not change when hovering over unit labels and prevent the user from clicking inside the unit label field?- in some way disable the unit label but not the numerical field itself
    thanks

    Which version of Labview are you using?  I ask so that you can find the tools palette.  In LV7.1 and older, it was under "Window" menu, with LV8.x, it is under "View" menu.
    Is the top box green? If so, it is in automatic tool select.  Click on it to turn it off.  Try repeating your steps.

  • Mouse pointer stuck at the right-hand corner of the screen.

    Hello all,
    I am writing to find help for my girlfriend in Nepal. She says the mouse pointer is stuck in the right-hand corner of the screen, and won't move. I suspect it's a software glitch but since I'm in the US, I can't look at it. This is an old G3 iBook in which we replaced the battery just before she left, and she reports that the battery may be connected to her problem. Anybody have any ideas for fixing this?
    Any help really appreciated!
    Thanks!
    mike simpson
    < Edited by Host, for your protection, no personal information please. >

    Hi, and welcome to Apple Discussions.
    If the iBook is running OS X 10.2 or above, have her try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
    If this works she will see the normal desktop. Once completely started up in Safe Mode, have her try to restart normally, and go to Applications > Utilities > Disk Utility.
    Select the named boot volume in the left sidebar, ("Macintosh HD" unless it's been renamed). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
    See if a little hard drive maintenance helps things out.

  • Mouse pointer is frozen at left hand corner

    Hi
    My USB mouse pointer is frozen at the left hand corner. I saw posts from users who have had same issue but did not find any answers.
    I have tried the following.
    1. Using different USB ports to connect the mouse
    2. resetting PRAM
    3. resetting SMC (I think thats what it is called)
    4. Cleaning the mouse
    5. Doing a hardboot
    None of this has helped.
    The mouse seems to work (e.g. I can click and it opens up the menu or if the screen saver has started, clicking the mouse stops it etc.
    Other info - I always shutdown my machine. I guess this is legacy of Windows days
    I dont want to reinstall the OS - that would also mean I have to update all the required OS updates post 2008 when I got the iMac
    Any one has a solution for this ?
    Thanks
    Tapan

    The mouse is bad, you can replace it with just about any Generic +(Logitec, Kensington, microsoft)+, a Mighty Mouse, a Magic Magic or the new Track Pad from Apple with your computer.

  • My mouse pointer jumps to the top left corner every second

    Hi
    I recently bought a Mac Mini, hoping to get into iOS development, everything was fine, but recently the mouse pointer has started jumping to the top left corner of the screen, this happens every time I try to move it, within 1 second of my moving the mouse, it's jumped back.
    It's made the system unusable.
    I've searched online and found other people saying that their mouse pointers jump every two or three minutes, but mine jumps within a second of me moving it. I have two Dell monitors attched via apple HDMI to DVI and Displayport to DVI adaptors. I've tried different mice, it's still the same.
    The problem is, even if there's a fix, I'm not sure that I could apply it, as I can't use the mouse at all.
    Can any one help?

    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, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • I updated my iMac to lion and now when i leave my desktop and it goes into stand by it like a picture is taken of the screen and when i want to log in the mouse point removes pixels so i can get to the user login screen this never happened ith snow leopar

    i upgraded my iMac to lion and now when i leave my desktop and it goes into stand by mode, its like a picture is taken of the actice desktop and when i want to log in the mouse point removes pixels so i can get to the user login screen this never happened ith snow leopard. does anyone else experience this and is there a fix?

    I have an iMac 8, 1 that I upgraded Leopard to Snow Leopard.  It was totally updated with the latest from Apple when I bought and tried installing Lion.  The upgrade failed, shot my OS and I couldn't boot.  Had the constant spinner on a grey screen..  did a format of the drive, hdd repair and everything came back clean... got back to Snow Leopard and all the updates on it again and then retried the Lion thing... same bs... dead duck.  Crashed my system one too many times.  I can't see where a few small changes, mostly app related can be classified as an OS upgrade and is not compatible with my iMac.  I have the stuff running on my Mac Pro but have yet to notice anything impressive.  I've always used F3 and really didn't require Mission Control.  Just open you app folder for launch pad... duh?  I use the hot corners anyhow.  As far as Safari is concerned... as a power user, Apple missed the boat on that for me.. full screen etc.. Wow.  I don't like the new Mail either..
    As you can see/read, I'm less than impressed with this release from Apple but I own so many of their products that I will have to put up with it for now... somehow the MS logo should apply to this release Steve.

  • Safari won't open and wheel (mouse pointer) keeps spinning

    Hi guys.
    I'm going crazy here as everything I've read and tried doesn't work?
    I've deleted cache files, history, plug-ins etc etc and every time I try and launch Safari, I keep getting the spinning wheel/beach ball/mouse pointer and safari doesn't open?
    I've received the following long error message and it may as well be in Arabic as I haven't got a clue what it means?
    Any techies out there who could shed some light "Error message for dummies' style please?
    This is the report error.

    You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
    Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    /Library/LaunchAgents/com.vsearch.agent.plist
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    /Library/LaunchDaemons/Jack.plist
    Restart the computer and empty the Trash. Then delete the following items in the same way:
    /Library/Application Support/VSearch
    /Library/PrivilegedHelperTools/Jack
    /System/Library/Frameworks/VSearch.framework
    Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
