Mighty Mouse - Erratic Behavior?

Hello all.. I'm now on my third mighty mouse, and all the ones I've tried so far are behaving quite oddly.
It's like the side buttons are stuck, or extremely trigger happy, and when I move the mouse around the side buttons are engaging multiple times per second. I have to disable bringing up expose just to use the mouse, but it's rather annoying because the clicking noise is quite loud, and almost continuous as I move the mouse.
I've installed the software, I've tried blasting away my com.apple.driver.AppleHIDMouse.plist or whatever, to no avail.
I don't think this is an issue with the user, either, as I've been happily using a Mighty Mouse at my work since about a week after they were released, and have no issues.
So this seems like something wrong with my OS install here (same version as my work), or the eMac in general. Help!
eMac Mac OS X (10.4.3)

I have been trying to troubleshoot the same problem since I got my Imac and MM a month ago. After two MMs, two trips to the Apple store with the computer and 4 unfruitful calls to support. No answers.
I thought I had tracked the problem down to an unstable electrical outlet, (the problem would go away at the apple store or if the computer was plugged into another outlet) the electricians could find no problem. Now the problem has resurfaced when plugged into a new outlet. It seems to be a grounding problem with the MM, or some kind of static electricity problem. If I grab the metal base of the Imac, the problem disappears.
The problem is also discussed in the thread: Mighty Mouse is freaking out!!
Does anyone have an answer to this problem other than a new mouse?

Bluetooth mighty mouse erratic

bought the bt keyboard and mouse on friday last....keyboard is fine but the mouse is a real disappointment with the mac pro. It clicks and scrolls ok but to move it around the screen is a horror. There's a lag, sometimes it's not controllable (i.e., i cannot get it to stop where I want or move it when & where i want). The settings have the tracking set to fastest (it is unusable at any other setting). It's a big disappointment since it is essentially more frustrating than usable. Keyboard is fine.

I have had my iMac since last October with the BT mighty mouse and keyboard. I never had a problem until last week. My mouse started lagging after waking up from sleep and the keyboard would intermittently lose comm.
About the time that this started happening, I remember having issues with my iPod shuffle. At first it did not recognize it when I placed it on the dock and then it started giving me errors that the device was not removed properly. I just gave up and that was when all of my mouse and keyboard issues started.
The next time I docked my shuffle, my iMac recognized it, synced with iTunes, and then I properly ejected it. After that, my mouse and keyboard have been acting fine.

Wireless Keyboard and Wireless Mighty Mouse performing erratically

I got the Apple Wireless Keyboard and Wireless Mighty Mouse as soon as they were available and I haven't had any problems with them until a few days ago. Now, both devices will "disconnect" for a few moments (the screen will show the "Connection lost" icon) and immediately reconnect.
The keyboard usually does it so quickly that it doesn't affect my typing. The Mighty Mouse, however, will sometimes slow down to a very erratic, choppy refresh rate - something like a dusty ball mouse cca. 1994. This usually lasts for about a minute and then fixes itself.
This happens several times per hour. I've tried restarting the computer, restarting the devices (replacing the batteries), removing them as Bluetooth devices and pairing them again, turning Bluetooth on the computer on and off... nothing seems to fix this. Both devices have fresh rechargeable batteries in them, showing nearly-full charge in System Preferences.
Is this a known or common issue? Who's to blame, the mouse and keyboard or the iMac? Has anyone found a reasonable fix?
Thanks.

Hi Neven:
See my thread about IDENTICAL situation:
http://discussions.apple.com/thread.jspa?threadID=1235070&tstart=30
The erratic behavior is identical, except that only my wireless keyboard is misbehaving. Unlike you, it has become a major hassle for me when I am typing and my keyboard disconnects mid-keystroke. Or, I'm reviewing a website or my work and the keyboard disconnects three/four times in two minutes. Last night, for instance, I was watching something on TV in the background and I saw in amazement as my keyboard just kept disconnecting and reconnecting every 30 seconds.
Otherwise, it is same, same, same: fresh batteries, no other bluetooth devices, 18" distance from the iMAC.
I noticed this began to happen AFTER I downloaded and installed last weeks' iMAC update.
So I reiterate my comment from my own thread:
+_*APPLE, ARE YOU READING THESE POSTS?*_+
There's a ghost in the machine.

Odd Mighty Mouse behavior?

Hi,
I have a brand new 24" imac with nvidia 8800 but my Wireless mighty mouse has started acting strange, jumping over the screen and making it impossible to use. I tried a wired mighty mouse and that's the same. I first noticed it after 10.3.5 upgrade but could it be a coincidence? I have done an archive and install back to 10.5.2 and it's still the same? It's not constant only intermittent.

Check for any dust in the LED hole. Try using a plain surface, like a solid colored mouse pad, if the surface is on the shiny side. If that does not work...
Try starting up from Mac OS X installation disc. If the mouse is also erratic when booted from another system, you can rule out the 10.5.3 update as the cause.
If it works normally when you are booted from the installation disc, there is probably some issue with your current installation.

Mighty mouse scroll ball behavior

Less than a week ago, I bought a Wireless Mighty Mouse. I thought that it was having trouble scrolling right, so I took it back for a replacement. This one seems to have the same problem.
The problem seems to be that the mouse has a hard time scrolling right. To scroll up, down, or left, I only need to put the slightest pressure on the scroll ball. To scroll right, I need to press the ball about halfway down. It's not that it's a problem per se, but the user experience is just off enough to be frustrating. As a small note, the mouse makes different noises when scrolling up, down, and left, versus scrolling right. For scrolling UDL, it makes a small clicking noise. Scrolling right makes a sliding noise. When I push the ball in further and scroll right, I get the clicking noise.
As I said, I've gone through 2 mice in less than a week. I thought the first might have been a fluke. Not that I've run into two with the same "problem", (and from two different stores), I wonder what's going on. It seems like it could either be a manufacturing defect that affected a whole batch, or perhaps this is the expected behavior. I can't imagine that my fingers are so oily that they would have gummed up the ball instantly. And yes, I have tried just about every cleaning method.
So the questions are: how does your scroll ball work? How much pressure do you need? And has anybody had problems only with scrolling right?

bytecrafter - I did some searching and found out a few tips that solved the problem for me.
First, I blew compressed air into the scroll ball. I pushed down on it with my fingernail so that the air could get into the crack.
Then I used a damp, lint-free cloth to rigorously clean the scroll ball, while the mouse was upside down. Apple has a video (and instructions) of this here:
http://docs.info.apple.com/article.html?artnum=302417
Hope that helps.

Erratic wired mighty mouse

I've just bought my first Apple MacPro about 6 weeks ago with a wired keyboard and wired mighty mouse. In the last week the mighty mouse has become very erratic in that it acts as if the back button has been pressed when ever the mouse is moved. In other words if I'm working on line and I touch the mouse even slightly the previous web page is brought up.
If use it in explorer or finder it brings up the previous directory.
This problem is present both in Leopard and in Windows XP running in Bootcamp.
Rebooting makes no difference
I've now attached an old Dell Logitech wireless mouse to a usb port and it works perfectly both with leopard and windows.
Any ideas?

I'm going through the same "issue" actually so I hope I can save you some time.
It's a grounding issue. You can experiment:
- Touch your Mac Pro system while you're moving the mouse, or;
- Touch your keyboard while moving the mouse
If the mouse calms down and doesn't try to escape , then you have the source of the problem.
I've read a lot of discussions on this, with people replacing their mice constantly, and even doing a full re-install. So if the above works, then your solution is in figuring out how to deal with the ground-ing problem.
What's more surprising is that Apple hasn't addressed this (it seems) for some time now. With all the gyrations customers go through, you'd think there would have been some type of solution (a recall perhaps?).

Odd Wireless Mighty Mouse behavior with new Mac Pro?

Hi,
I have a brand new Mac pro and Wireless Apple Mighty Mouse & Keyboard.
The mouse however is not operating properly, it is jerky and slow to respond on a intermittent regular basis. I can move the cursor around the screen but it will stutter and jerk slowly then pick up ok?
I had the mouse and keyboard with my iMac and it worked fine. I have run all updates and re-installed but to no avail. The keyboard is fine.
I suspect it's a hardware issue with my new mac Pro but i'd love it if someone has any other possible causes.
Thanks.

Hi, there's a quite a few people with similar problems, including myself.
My keyboard likes to drop it's connection for no apparent reason, which in turn likes to mess up my mouse and cause it to stutter for a while. Pairing up new devices can do this too, I've found.
It's been thought that some Mac Pro's came with their WiFi and BT wires incorrectly fitted, if you have a search you should find a link to the tutorial if you want to try switching them around.
That said, it didn't make any difference to my BT keyboard and wireless Mighty Mouse, so I switched them back.
I've been hoping for a software fix, but no joy so far, glad I got a three year warranty as standard.

Wireless Mighty Mouse has stopped selecting, cutting or pasting

My batteries ran out two days ago. I changed the batteries but since then my wireless Mighty Mouse will not select text, cut or paste. It has other erratic behavior. Any help and advice welcomed.

Sending back to Apple. Free refund.

Mighty Mouse Battery Life

Hey there - what's the battery life like on the Mighty Mouse? Also, what's the battery life like on the Apple Bluetooth keyboard. I'm currently weighing up between those or the Logitech wireless keyboard and mouse pack.
Thank you!

Hello,
I have been using a Microsoft Notebook Laser Mouse until it recently started acting erratically with my MacBook Pro. I had used it for some months with an older iBook with mostly good results. It was less than 9 months old when it went bad for good.
I looked at many alternatives and read user reviews of all wireless and bluetooth versions. In the end I too went with the Apple Mighty Mouse. Quality, like pretty much all of the rest of Apples offerings is first-rate (been a Mac user for 8 years now).
I've only had it for a short time but I feel the response and solid connection make it worth the extra cost. The old saying "you get what you pay for" applies here. I have not noticed any strange behavior that others have reported and don't expect to. Apple's hardware just works in my humble opinion.
Good Luck
Cheers.

Mighty Mouse click happy

I'm using my Mighty Mouse for the first time today. I noticed lots of erratic behavior on my desktop and between open windows, then I picked up on what sounded like repeated clicks. Sure enough, my MM was rapidly and repeatedly clicking on its own, without any prompt from me. It appears to be sporadic, but I finally had to disconnect it in order to get some work done! Is this new-user error or what??

I had 2 new mighty mice doing the same thing. But not
only are they clikcing - they are also
activating/deactivating exposé repeatedly. Both
systems were running at the same time when this
started. I have an airport extreme network.
Same issue with my mighty mouse on my iMac G4: When I touch the upper case surface with my fingers (not fingertips but complete fingers) -without actually pressing down the housing- the mouse performs the side-button action. I called Apple and they sent me a replacement mm, but it has exactly the same erratic behavior.
Both mice work fine with my other Macs by the way.
So I deleted my harddisk completely, performed a PRam and NVRam reset, reinstalled 10.3, reinstalled 10.4, but absolutely nothing helped.
The issue apears as soon as the Mac is switched on and recognizes the mouse - even before OSX is starting to boot.
I hope there will be a patch for this bug soon!!!!

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.

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.

Mighty Mouse shortcuts changed

I'm using a wireless Mighty Mouse on OS 10.5.8. The track ball is set to Button 3 and when in a web browser, would open a new tab when clicked once. For some reason, its now acting like the Secondary Button (opens the sub menu). There used to be a mouse shortcuts preference window to set this, but I can't find it anymore. Does anyone know how I can modify the behavior of the button 3 for Mighty Mouse?

You will need to use software such as USB Overdrive to set one of the buttons to the Home key.

Mighty Mouse Random Clicking

OK, so the search function is disabled until tomorrow, so please don't flame me for not searching...
Starting this morning, my mighty mouse (wired) started clicking (second button clicking, I think) randomly, preventing me essentially from using it as it would continuously click while I tried to work, pushing my current application into the background. Am using a wireless Microsoft mouse as a backup currently.
I have tried disconnecting and reconnecting the mouse numerous times, and have even unplugged and replugged the power supply (UPS) in case there was some kind of "lost ground" issue.
I am a new iMac user about to drop my Windows machine altogether, and this clicking problem is driving me crazy! Any suggestions?

I might have found the solution to your problem.
I just purchased an iMac for a friend, and was telling them how Mac's are a lot better than PC's. We removed his old PC, threw it aside and set-up his new Mac. When it was all set-up the mouse started to do this crazy clicking and entering Exposé randomly, also the right click function would not work.
My friend was not impressed with his first experience with Mac.
Anyway, we called Applecare to no avail, they didn't have a clue of what was happening. I then took the whole computer back to the store and they set it up at their shop to test it and it worked perfectly. I stood there scratching my head. I took the computer to my place and it worked perfectly there all day.
Later I took it back to my friends house and guess what? They mouse is going all crazy again.
We tried setting it up in different rooms in his house, also to no avail.
At this point we where going to return the whole system and get another one. Then I decided to use trusty Google search and I found this article in some forum www.macintouch.com/readerreports/mightymouse/topic4048.html I scrolled down and read many others with the same problem and what they did to solve the problem.
From the forum I gathered that there is a design flaw in the mouse that Apple doesn't know about. It makes the mouse extremely sensitive to your body's static electricity because it doesn't have proper grounding. That is why your Microsoft mouse works and the Mighty Mouse doesn't. I further gathered that the reason it worked at my house and not at my friends is probably due to bad earth connection at his house or to some appliance interfering with the static in the air.
The bad earth connection theory was pretty much proved by people stating that when they touched the metal case or the metal keyboard with one hand, and using the mouse with the other, the erratic behaviour would stop. Why? because you are earthing the static in your body through the metal on the iMac. Try it yourself, it should work.
There are 2 solutions to this:
1. Get an qualified electrician to come to your house and check that the earth is 100% at your house.
2. Get another mouse until Apple acknowledge the problem and fix it in their next batch of Mighty Mouse.
I didn't want to spend big buck to get an electrician to check the whole house, so I am opting for the second solution and taking the wired mouse that came with the iMac and swapping it for and unwired version, hopefully that will solve the problem. I'm going into the shop today, I will let you know how I went.
Sorry for the long response, but the more info you are armed with the better a fight you have to get Apple to solve the problem at minimum cost to you.
I hope this helps you

Mighty Mouse tracking issue while downloading files

Hi everybody ...
I'm the owner of the Wireless Mighty Mouse... For about 2 months I'm recognizing a strange behavior.
When I do start a download via Safari (I'm connected to the Internet via Wifi 54Mbits (2,4 GHz)) the mouse tracking start to bucking. During the download no fluent motion occurs. After the download finished the bucking stops and the tracking flows seamlessly. Does anyone have the same problem? I'm not quite sure what the exact problem is but could this behavior result from the connectivity frequency of bluetooth and wifi? And please don't tell me to reset my keyboard or my mouse. I already did that. I also updated to the latest official software update for bluetooth.
Please help me.
Thx destinationCloud

Hi,
I have the same problem, but mine usually shows up when I have MS Word opened for a while. It is as if there is some other process cycling that interferes with the tracking. Sometimes it shows up as a major lag (cursor stutters and moves a little bit for a large hand motion) or the cursor jumps way across the screen. It isn't always when MS Word is opened, but more frequent when it is (occasionally with Pages too). Changing batteries doesn't help, changing surfaces doesn't help. After some time, the problem resolves and mouse moves smoothly again, for a while. This has been more of a problem in the last few months than before.... was the Bluetooth driver changed? Does it have anything to do with a cache that is used before changes are saved?
Where is the Bug Report link... I can never find it. Just put it right on the Support page please, BIG.
