Wireless Mighty Mouse interference under Leopard

Hi.
I recently upgraded to Leopard and I'm experiencing interference with my Wireless Mighty Mouse since: the cursor starts jumping erratically. The thing is - this only happens when I'm doing *Java debugging in my Eclipse IDE*. For the rest of the time, it works pretty much OK (may still jitter on occasion).
I'm using TimeCapsule in 2.4 GHz, this caused some problems before I changed the default channel. I powered it down completely and I'm still getting the same interference. This is not due to heavy CPU load - in other cases of heavy CPU usage the mouse works fine. I also tried switching to a wired MS mouse or using the TrackPad and it works OK.
Any clues?
Thanks,
Zviki

Thanks to the good people in java-dev mailing list, I found that it's spindump causing the slow-down. When the application hits a breakpoint it becomes non-responsive. The system decides it's time to activate spindump to dump the process information, in order to "report the problem".
This is totally wrong behavior. Spindump eats the CPU, making the mouse unresponsive.

  • Issues with Bluetooth/Wireless Mighty Mouse since Snow Leopard Install

    Hi,
    I am having issues with my bluetooth wireless mighty mouse. It was fine after initially having installed Snow Leopard. However, in the past week it has become progressively more and more unresponsive. It functions perfectly normal for the first while after startup, then after a short period of time it becomes slow to respond to the mouse movements that move the cursor. Eventually it gets to the point that moving the mouse results in no cursor movement whatsoever. It also becomes unresponsive to squeezing the side buttons. There are no issues with clicking or scrolling with the track ball.
    I have searched the discussion forums to find issues that pertain to "bluetooth" and "wireless mighty mouse" and have tried the following suggested remedies... Repairing my Mouse with my Mac mini. Renaming my mouse. Deleting the com.apple.Bluetooth.plist file from Macintosh HD\Library\Preferences and restarting my Mac. Reset PRAM and NVRAM. Also tried to install Bluetooth Firmware update 2.0.1 but I get an indication that the update is not needed on my Mac mini. I have also checked for software updates but there are none...
    I am going to attempt resetting the SMC but am doubtful that this will help...
    Can anyone help... Please... ?
    Thanks,
    Des

    I had read in another forum where someone had an understanding that the bluetooth problem had something to do with Airport/Time Capsule. I had also read about how someone was having an issue with being unable to turn off airport. (I had this same problem.)
    Upon deleting a few airport related plist files (see below url) I was able to turn off/on airport AND my Mouse issue has no longer appeared... everything is working a-ok now.

  • Wireless mighty mouse and Log In/Out

    I have been having some issues with my wireless mighty mouse under Leopard. I have noticed that if I am logged in under one account and log out the mouse no longer will move on the screen. The "Right Click" functionality if available but the movement is not. I also have seen this behavior when logging out of an account and then logging into another account. I have tried disconnecting the mouse and then reconnecting it but that does not seem to solve the problem. The only work around is to log out using the keyboard and then log back in. I was wondering if anyone else has had any similar problems or knows of any solution to this.
    Thanks

    I have noticed that if you log in/out with the mouse then I do not have the problem. But If I use the keyboard shortcuts to log in/out then the issue occurs. Possible bug?

  • Does Time Machine Backup irritate wireless Mighty Mouse?

    Hi there. I'm having a strange issue here. With an iMac that came with bluetooth mouse and keyboard, OS out of the box (no software updates installed because there's no internet connection), each time Time Machine is backuping files, the Mighty Mouse is acting weird. It actually feels like someone else is working with it. Even if I do not use it and leave it alone, the pointer goes wild on the screen. Trying to work during Time Machine backups is impossible, because I cannot use the Mouse properly.
    Does anyone of you have a similar, if not, the same issue? Any ideas?
    Thanks in advance,
    later, Stephan

    I am having a similar problem with my IMac and Time Machine. During wireless Time Machine backups, the wireless mighty mouse and wireless keyboard disconnect. If the mighty mouse remains connected, it moves very slowly and is virtually unusable.
    So far I've thought of two potential problems to troubleshoot:
    1. I experience this problem when I connect to the Time Machine through the "802.11n (802.11b/g compatible)" wireless connection (set in the AirPort Utility), but I don't experience the same problem when I connect to the Time Machine through a wired ethernet connection. So it appears the b/g compatible setting is causing interference. I haven't tested to see if the "802.11n only" wireless connections causes this problem or not.
    2. I also wonder if the IMac does not have enough RAM to complete the wireless backup. My IMac has 2gigs of RAM, and during backups it maxes out. I plan to upgrade to 4 gigs to see if the problem continues. (Stephan, how much RAM to you have installed?)
    peace,
    Marcus

  • Wireless Mighty Mouse Sputters During Network activity

    Has anyone figured this one out yet.
    I have a wireless mighty mouse that when you copy files to or from a computer off a network,
    it sputters and barely moves when trying to use it. If i plug in a usb mouse there is no problem at all.
    Was using a verizon wireless router and just bought an airport extreme. Guess what. Still does it. When I hard wire my computer to the router all works fine.
    I just cant think of what this could possibly be. Any help would be appreciated.
    Thanks.

    There are a lot of people with this problem - mostly MacBook owners, but probably because they're more likely to have the wireless and BlueTooth running.
    I have the problem with a Logitech mouse on a Mac Mini -- cursor goes bonkers at random intervals, with terrible mouse lag, and I basically can't use the mouse when it's happening. It doesn't correlate with anything I can see in the Activity Monitor, but I can stop it if I turn off BOTH Airport and the router.
    Not likely to be RF interference with the signals, IMO, but some have reported that switching to an 802.11n router (or 802.11g with b compatibility disabled) solved the problem.

  • Wireless Mighty Mouse Pointer not moving

    Need some advice. My 7 month old IMAC wireless mighty mouse is scrolling fine but does not move the pointer...can someone help? Thanks!

    Hi Rich:
    That file is located in Macintosh HD>library>preferences. Sometimes (rare, but it happens) preference files become corrupted - causing all sorts of odd behavior.
    If that does not help, try resetting the PRAM:
    http://support.apple.com/kb/HT1379
    If that does not fix the problem, take the mouse to an Apple store or call Applecare and indicate you have a warranty issue. Apple does replace things under warranty at no cost (shipping paid both ways). I have had a mouse and keyboard replaced in the past and was pleased with the service.

  • Wireless Mighty Mouse Replacement

    I dont know to whom I have to start begging, to actually get this done... But for the love of all that is good on this Earth, can Apple PLEASE replace my wireless mighty mouse, with a wired mighty mouse.
    I've only owned my iMac for a few months, everything works fine, still covered under Apple Care, I just need to downgrade this mouse. The weight of this thing and how quickly it runs through batteries is becoming an issue for me. I'm a Tech Lead for a support call center, and regardless of policy I know this can be done if the right person gives the green light for it. You guys can keep the difference in cost, I'll provide whatever information is needed, I just really want to downgrade this mouse to the wired version...
    *PLEASE PLEASE PLEASE*
    Thank You,
    Charles

  • Wireless Mighty Mouse Looses Right Click Functionality

    I am using a new Wireless Mighty Mouse (about one month old) With new batteries.
    Since I started using it, the (secondary) right click would stop function after repeated use. After many frustrating trouble shooting attempts, I discovered that the Right Click will work again if the mouse is left idle for about 15 - 20 minutes.
    I will like to know if this is a defect that's inherent in the Mighty Mouse system, and if so, has anyone found a solution to this problem or is there a fix?
    Any input would be very much appreciated

    Unfortunately my experience suggests no. I'm on my 5th (or is it 6th?) wireless Mighty Mouse now, and they've all behaved just as you described. The latest replacement was only a week ago. I suspect the only point in replacing it further times would be to demonstrate that you've tried all you can. As far as I can tell, my only recourse at this point is convincing Apple to refund me, which is a shame because I like the scroll ball design.
    I should note that I'm in Australia, in case stock has been slower to update here, but it shouldn't make a difference...
    I've noticed that the problem seems to occur a lot more frequently under hot conditions - room heater on, hot hands etc. Could it still think the left button is being touched because it's warm and/or sweatier than usual?

  • Wireless Mighty Mouse Name Changes

    For the past 5 months, I've used the same wireless Mighty Mouse without issues. During that time it retained the name I gave it upon setting it up for the first time. Then this morning (3/15), I go on my Mac and see it is label as "[MyLastName]'s mouse" and then after a few moments "[MyFirstName]'s mouse." I tried to change the name back, but I don't have the rename option under the Bluetooth cogwheel, only update name is available. Any thoughts?
    This may seem trivial, but I always get concerned when something on my MBP changes suddenly. Thanks!

    HI
    Mine works...I had to have it manually recognize the bluetooth mouse and install it. Right click the bluetooth icon in the lower right bar on windows and then go thru the recognition and install. When I boot up into windows, takes about a minute after finishing booting for the mouse to be recognized, but it works OK then

  • Wireless Keyboard + Wireless Mighty Mouse questions

    Hey everyone, Mac users please don't hate me for asking this but I have some questions about using the Apple wireless keyboard and wireless Mighty mouse on a windows XP PC (Not in boot camp).
    I have already bought the wireless keyboard, and have it working with my Windows PC using a Belkin bluetooth dongle, and was just wondering why the Control + Alt + Delete combo on the apple keyboard of (Control + option + Fn + Backspace) isn't working for me? I think it may be something to do with the keyboard being wireless, or possibly the Fn key will not work in Windows? I also would like to be able to remap some of the "F" keys on the wireless keyboard to windows functions like the volume and playback/ pause media keys. Is there any software anyone can reccomend which will allow me to do this?
    My second question is about the wireless mighty mouse. I haven't bought it yet, but I have strong intentions of doing so and using it with a Windows XP (to be updated to Win7 when it gets out of beta ~Sept) PC. I love apple hardware- peripherals especially, which is why I already bought the wireless keyboard and now wish to buy the Mighty mouse along with a 30" Apple display to use with the PC in my office at home. I have read mixed reports on many Mac forums about the compatability of the WMM with Windows, and have come here to get it cleared up before I spend close to £50 on a mouse that may or may not work. I heard somewhere that some but not all functions of the mouse would work in Windows, whereas somewhere else I read that a guy had installed a driver that was extracted from a (I think Leopard) Mac install disk and that the mouse was working 100% on his XP or Vista PC.
    Any help would be greatly appreciated guys, I built myself a special edition of one of my own design Eclipse series PC's to put in my new office at the start of this year and normal monitors/ peripherals just dont look right in that room because its very minimalist and modern and Apple make the most minimalist but functional hardware I know, which is why I want to use this KB/Mouse/Monitor combination.
    Thanks,
    Matt.

    I'm REALLY interested in how you got your Apple wireless keyboard to work on your XP PC. Was the keyboard recognized and working immediately? I've been reading thread after thread; still can't figure it out. Can you provide any help? Thanks.

  • Bluetooth not working = wireless mighty mouse not working too

So it's surely in my imac the problem. Is there a way i can fix it buy myself or i have to send it to an apple store?
    N.B. i have the same problem as the rest of the peps who have the latest update of Leopard

  • FCP 5.1 and Wireless Mighty Mouse

    Just an informational post:
    I have had my wireless mighty mouse since July 27th, and it works well with FCP 5.1 on my G5 Quad. I had abandoned my old wireless mouse (both the Apple and "The Mouse BT") because of jerky operation, delays, lack of precision, etc. I started using a wired mighty mouse
    The new Wireless MM works even better than my wired MM; the new laser sensor is more precise, and there is no lag. It works on my wood desk top as well as on the matt black mouse area on my keyboard tray. My G5 is 5 feet away and to the left of my work position, under a wooden desk; there are not metal obstructions between the mouse and the BT antenna.
    I really like the scroll wheel (both MM's) for horizontally scrolling the time line as I edit. Used in conjunction with a Shuttle Express, I have all the editing control I use at my fingertips.
    YMMV

  • Wireless Mighty Mouse won't work properly with MacBook/tech support stumped

    Hi. First post. Anyone heard of this problem? Appears to be location-sensitive. Problem described below, but first, short background...
    Just bought entire Mac system after decades in corporate world with PC. Believed the TV ads that it would be simple. Already have been back to Mac store 6 times and have spent roughly 7 hours on phone with help line. Mac store even replaced Macbook entirely in case it was faulty logic board/Bluetooth circuit -- didn't help. Also, problem doesn't happen in store. So, to get to the point:
    Wireless Mighty Mouse doesn't work properly when hooked up to Macbook -- herky-jerky, slow, unresponsive, sluggish, imprecise, intermittently better/worse. Went through a few Mighty Mouses and finally gave up; now using hardwire mouse and there's no problem. But before I return Mighty Mouse for refund, would like to see if there's a solution b/c I'd prefer wireless.
    System is the latest little souped-up Macbook, 23" HD Cinema external monitor, external wireless Apple keyboard (which works fine), wireless Mighty Mouse (the culprit), Airport Express, HP printer. All brand new from local Mac store (Fifth Avenue, New York)... where the Genius counter folks have given up. I'm not convinced they believe me because (a) the problem doesn't occur there, and (b) after a couple of new Mighty Mouses, they finally just gave me a new Macbook to make me go away... but after going through the whole system setup once again, same problem. Have tried many different mousepads, BTW.
    Tried all the stuff phone tech support suggested -- removing/installing/reinstalling software, etc. Airport works fine; using modem and printer connections there. Bluetooth works fine with keyboard. I've scouted around for intefering devices; even unplugged electrostatic loudspeakers and old tubed amps in living room (concrete wall separates rooms), unplugged hifi in same room, etc. On 40th floor of Manhattan hi-rise; concrete walls between neighbors. Have never had interference before with anything; previous PC system worked fine with Microsoft wireless (optical) mouse.
    This is no longer urgent because hardwired Apple mouse works well. It's just mysterious.
    Any thoughts?
    Other than that, I like the Mac environment so far. Fifth Avenue store is cool, also, because it's open 24/7.

    Hey, thanks! That was fast. I'm impressed by the Mac community.
    This program helped my hardwired mouse, actually, and did give me wider parameters on the wireless mouse, but it didn't correct the herky-jerky/sluggishness -- actually amplified those problems.

  • Windows 7 and Wireless Mighty Mouse, Wireless Keyboard and sound problem

    Hi,
    I just installed Windows 7 x64 Ultimate on my iMac 24" white ( OS X Leopard 10.5 ). Surprisingly, it installed without any problems. The only problems I have now are the Wireless Mighty Mouse and the Wireless Keyboard ( alu ).
    After I installed Windows I inserted the Leopard Instal DVD and installed Boot Camp. I got a message right away saying that: "This program has known compatibility issues...". I clicked Run program and continued. Soon I got the same warning, but this time not for Boot Camp, but Intel Chipset Device Software. I clicked Run program yet again and it continued installing. Then I got a different warning: "Service KeyAgent' failed to start. Verify that you have sufficient privileges to start system services." I clicked Ignore and installation continued. I got another "Service Mac HAL' failed to start. Verify that you have sufficient privileges to start system services." warning, clicked Ignore again and after that it finished soon and I restarted the computer.
    When I came back into Windows there was no Apple folder anywhere or any sign that I have just installed Boot Camp ( should there be? )
    I installed Boot Camp Update 2.1 for Windows XP ( because Vista x64 version wouldn't start ) and basically I got the same warnings I did when I installed Boot Camp from the Leopard DVD ( described above ). I also tried to instal Boot Camp Update 2.2 for Windows, but it didn't start. I also downloaded Bluetooth Update 1.0, but all I got was a message saying: "This update is not intended for this computer and will not be installed.".
    There is also no sound.
    This is basically it, I really hope some of you who run Windows 7 with wireless keyboards and mice can help me, because I desperately need this to work ( I use a Windows only program for school ).
    PS. I have a 2007 iMac 24" white and while it is not on the we're-not-supporting-that list for the infamous Windows 7 Boot Camp update, all other iMacs from its generation are. Any ideas?

    Found a solution for the "Boot Camp x64 is unsupported on this computer model" message. Here is the link: http://www.techulous.com/hardware/how-to-apple-boot-camp-64-bit-for-windows-7-on -unsupported-macs.html
    Everything works ( for ) now. Yay!

  • Apple Mighty Mouse: covered under AppleCare?

    I've got a Mighty Mouse that is connected to an iMac that we have in our lab. The mouse has stopped working altogether (no response no matter what computer it's connected to).
    The iMac is registered under an AppleCare agreement for 3-years and it's still under warranty for it. My question is: does that AppleCare agreement extend to the peripherals that come with the computer? Would Apple be able to replace the mouse, free of charge? Or repair it?

    Yes. My wireless Mighty Mouse went bad (made grinding noise) and they replaced it under the AppleCare program. I didn't feel comfortable giving them my credit card but it was quickly credited once they got the old one back. No charge to me for shipping either way. A painless experience! Yahoo for Apple!!!
