Why isn't my wired Mighty Mouse scrolling down?

Some days like right now my wired Mighty Mouse that came with my late 2007 20" aluminum iMac doesn't want to scroll downwards. The scroll ball scrolls upwards and sideways perfectly but doesn't want to scroll down. Why is it doing this? I tried cleaning the area of the scroll ball but still nothing. Please don't say that I need a new mouse.

I have the same problems with my less than six weeks old 24" iMac & two yr old macbook: i always wipe my hands before using them. I have tried most suggestions on this forum and others to no avail.
I could probably get a replacement thru apple care for my iMac, but since the problem is so prevalent, another mouse is not a viable solution.
At this time, I actually prefer using an old cheap wired mouse that was in storage .
To those considering another brand, I had random waking & waking only with restarting issues with a wireless logitech mouse on my macbook.

Mighty mouse scrolls down but not up

why is my mighty mouse scrolling down but not up on my browsers?

Usually it is accumulated crud: skin oils and flakes of skin and dirt, but some have been accepted for repair by Apple. Occasionally a restart fixes the problem. If not there was a recent discussion that yielded several promising suggestions:

These included cleaning the ball with a soft cloth, cleaning the ball with a baby wipe, and disassembling the mouse to thoroughly clean the interior.

Mighty Mouse Scroll Down Issues

Hello, I have a wired Mighty Mouse that I use with my Mac Mini. For awhile my mighty mouse will scroll up, and side to side but it will not scroll down.
I have used a lint free cloth and tried cleaning it vigorously upside down with the felt cloth as well as other objects with no luck. It is not within coverage so I was wondering if anyone has had some other resolutions for this and please no answers like "Buy a new mouse". I have another mouse but I want this one working.
Thank you for your time

Isopropyl alcohol. Preferably 95% but I've done this with the typical 70%, so whatever you have in your medicine cabinet. With Mouse unplugged (powered off, battery removed for wireless mice,) put the mouse on a paper towel and pour a small amount of alcohol over the ball. What you are trying to do is get some alcohol down past the ball and into the internal rollers, which have some gunk on them that you're trying to remove. Isopropyl alcohol will not corrode the electronics and will help loosen and break up the gunk. Roll the ball and pour a little more. Repeat a few times. You will want to let everything dry as much as possible before using. Thus pouring a small amount and not the whole bottle and not "dunking" the mouse in a bowl filled with isopropyl alcohol. Do that only if you get really desperate, but if you do, then let it drip and air dry afterward.
There is not much space for the gunk to be "flushed" out so eventually this may not work. At which point you can look on Youtube and see several tutorials on disassembling the mouse. The mouse is glued together so this is not without risk. You may end up just buying a replacement mouse so just be prepared before attempting disassembly or even the alcohol.
(In case you're concerned, isopropyl alcohol has been used for cleaning around electronics for many, many, many years. Used to clean water/syrup/milk/juice damage since it doesn't corrode the circuit boards. While it generally doesn't conduct electricity, it was generally discouraged to use it on live equipment for various reasons. And due to skin irritation, gloves often were used, but in this case with the mouse and the small amount being used, it's up to you to whether you want to use gloves and eye protection.)

My wired mighty mouse no longer scrolls down - only up and sideways.

My wired mighty mouse no longer scrolls down; only up and sideways. It could be a hardware problem and I guess I should go and by a new mouse but before I do I thought I'd check whether there was any parameter I could change to fix or test this. Anyone else had this problem? Cheers.

Wired Mighty Mouse lacks Scrolling Options

Hello,
Is there a way to enable zoom-scrolling on a wired Mighty Mouse?
I was reading Mac Help on mouse settings and noticed a feature that I've never noticed before: Scrolling Options. Help claims that this feature allows to customize the scroll-ball behaviour, including 360 degree scrolling and zoom-scrolling. Alas, I failed to find this feature in my Keyboard & Mouse pane.
I searched on Google, and it seems that this feature was introduced in the new driver that ships on a CD with the new wireless Mighty Mouse. Look here: http://tinyurl.com/pyx7s.
Will this new driver work with the wired Mighty Mouse? if yes, where can I get this driver?
—barmalutka
Mac OS X (10.4.7)

The Zoom function appears to be giving the wireless MM access to the Universal Access System Preference "Zoom" feature.
The MM already has 360° scrolling. I sense that the pulldown menu you see in the System Preference Pane for the new wireless MM probably gives you control to limiting the direction of the scrolling to left-right, or up-down and possibly diagonally.
Who knows, if we are lucky the new MM System Preferences may appear in a future OS X update.
Until then these 3rd party mouse System Prefs are available;

Wired Mighty Mouse cannot scroll down.

I have had my wired mighty mouse since 2007. Every once in a while the scroll would stop working for a second but once i rolled it around, it would start scrolling again. Now my mouse has not been able to scroll down all day. I have read online that if you roll the scroller around on paper, it will clean the roller and it should start working again. I tried this many times and my mouse is still not functioning. Is there a way to fix this or should i just purchase a new one?

You need to open & clean. Watch this video.

Wired Mighty Mouse vs. Wireless Mighty Mouse

Hey, my wired Mighty Mouse track ball just crapped out on me (I can't scroll down anymore) so I guess I am looking to buy another one.
Does anyone have any experience and/or opinions on the Wireless Mighty Mouse track balls being any more reliable or longer-lasting than the Wired Mighty Mouse track balls? Or are they both pretty much the same quality-wise?
Many thanks.

Trust me, copelander, a mighty mouse that will not scroll in one direction is almost always simply dirty. I have two (one BT one wired) each of which I bought very soon after they first came out. Essentially failure to scroll in one direction means that one of the four directional sensors that it relies on has got clogged.
Cheby (above) describes the usual solution very well. Simply disconnect the mouse, hold it upside down, and rub the ball vigorously in all directions on a clean piece of paper. Try to avoid "running over" any of the tiny black specs that will probably appear on the paper , as the ball is good at picking them up again.
If things have progressed beyond the this, the tip of something like the plastic toothpick that comes with swiss army knives, or a cable tie, worked gently in around the edge of the ball, can help, but be gentle so you don't damage the mechanism. Some people also use a dab of isopropyl alcohol on a clean cloth applied to the ball.
To keep your MM running smoothly for a long period, clean it using the "rubbing on paper" trick AS SOON AS you get the slightest sign of bad scrolling, or every few days, whichever comes sooner. Once you have done this for a while you will find that the problem becomes much less frequent, as the internals get rid of any accumalated residual gunk.
People who smoke, and those whose hands get oily or grubby for one reason or another, seem to have more problems with this issue, and might want to think about a regular 'wheel" mouse instead, but I've found that a minute of preventative maintenance every few days keeps my MM's scrolling beautifully in all directions. I haven't noticed any difference in the behaviour of the wireless or wired models in this respect. They both use the same scroll ball mechanism, so this isn't surprising.
As far as choosing between a wired and a wireless one goes for use with an MBP the wired one is lighter, and probably uses less battery than having bluetooth running all the time. On the other hand, the BT one can be handy if you are working in cramped quarters, and don't want a jumble of wire to deal with.
Cheers

Will any wired MIghty Mouse still work with my G5?

Unfortunately, my Mighty Mouse has reached the impossible-to-clean-trackball-anymore stage. It just won't scroll up anymore.
My current Mighty Mouse dates to 2006 or 2007. I wish I knew the exact model number beyond A1152.
Must I be concerned about what model Mighty Mouse I buy to replace this one? I know they came out with some zoom version. I don't care about the zoom. I just want the basic scrolling (I don't even use the side buttons; just click and scrolling).
Will any model of wired Mighty Mouse be okay?
Thanks so much!

"Unfortunately, my Mighty Mouse has reached the impossible-to-clean-trackball-anymore stage. It just won't scroll up anymore."

BTW: Before purchasing a new MM, update your OS to 10.4.11 along w/all the updates that goes with it through Software Update.

Wired mighty mouse setup.....

Good morning.
Any anybody point me towards basic setup instructions for the A1152 wired mighty mouse (NOT current "magic mouse")?
What do the buttons do singly and in combinations, scroll button antics, etc...........
I haven't been lucky in finding this on the web.
Thanks for your time.

Mighty mouse scrolling problems

I'm having trouble with my mighty mouse scrolling. It was working fine now not. I just replaced the batteries after indicatortold me to do so. I've tried re-loading the software (though the install routine called it an upgrade).

Mine wont scroll down.
Up, left, right no problem.
If I put the mouse near my ear I can hear a soft clicking when I scroll up, left or right, but no sound when I scroll down.
I have tried cleaning and pressing hard, etc.
I just got off a 47 minute troubleshooting session with apple support and they finally agreed to replace it. I can't believe how nontechnical and unknowledgeable the level 1 support at apple is. It was clearly a mechanical trouble and I described it very clearly, yet they insisted on making me log into other accounts, check preferences, replace batteries, etc. On top of that I was put on hold several times while the tech checked with others about what to do and filled out forms, etc. I have to say I really am not happy with apple support based on this and all previous experiences. On top of this I have to give a credit card# as collateral until I send the defective unit back. If that is the policy why don't they save the 47 minutes and just process the replacement just like the cell phone companies do??
Oh well. Good luck to all of you with your mouse problems..

Mighty Mouse Scroll Ball always breaks

Hi, I have a 2 month old iMac, and This has been a problem for about 6 weeks, but I haven't gotten around to posting it. My mighty mouse scroll ball breaks repeatedly and I have been fixing it, but it is a real pain. Don't suggest not using my mighty mouse, because I love and hate it, I love how it has multiple buttons, but hate how the scroll ball breaks all the time, can someone help me?

It just needs cleaning. Use a damp cotton rag and vigorously move it across the mouse ball. Do this for about 30 seconds. BTW, there are instructions in your owners manual about this. This is from page 63 of your Users Guide:
*Cleaning Your Mighty Mouse*
You may need to clean your mouse from time to time to remove dirt and dust that has
accumulated in the scroll ball area. Hold the mouse upside-down and roll the scroll ball
vigorously with the cloth that came with your iMac, or another clean, soft, lint-free
cloth, to help dislodge any particles that may interfere with proper scrolling.

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?).

Wired Mighty Mouse and right click on my intel imac

Hi,
This is a stumper!
1) Wired mighty mouse stated to lose right click functions. Control click
works fine but right click with menus is gone.
2) Tried steer mouse. No change
3) Deleted hidmouse user prefs. No change.
4) System Archive and install. no change
5) Clean install and Account reinstall (by hand). no change
6) Nuke and Pave. no change
7.) Pram reset. no change
8) Mouse works on other Macbook- not a mouse problem.
9) Second Mighty mouse exhibits the same problem.
10) logging into second account. no change
11) Other 2 button mice work!
12) I like my mighty mouse, but I need right click!!
13) Tried Apple Dev hid driver debug . no change
14) Tried a bunch of other things but this has me stumped....
(and I'm Apple Certified) any other suggeestions or software
I can try? Context plugins are ok...but I'm not sure if there are other prefes to deleted? Also, a totally fresh install should have fixed this...what's going on here? I need to know.

What is strange about my mighty mouse which also experiences similar issues is that you have to be careful where you are pushing it. My right tbutton is set as a control click but if I don't push it in the very upper right hand of the mighty mouse it behaves as a single click. The left hand button, as such, does not seem to be as sensitive to placement as the right hand one. For a long while I could not get it to work at all, until I figured out where I actually had to strike it.
I had never used a mighty mouse until I purchased a new iMac a couple of weeks ago and just figured it was "operator difficulty" as I am far more used to a trackball than a mouse. I may still go back to one if I can't get used to this mouse. I think you really have to put your whole hand over the mouse to make it function properly and I tend not to do that.
Does this help you with your issue? I am not sure, maybe there is some sort of difference in the way the mighty mouse works with new hardware?
Good Luck! Wish I had more to offer other than trying carefully to position your handin difernt places and see if that helps.

Wired mighty mouse makes clunky noises

Hi, my two month old wired mighty mouse has started making loud clunky noises when I use it and when I press gently on it it seems loose, I can get it to make that noise just by pressing lightly on it. It works fine, it's just not quiet like it used to be and like my old was one for 3 years. It seems like a mechanical problem.
Does anyone know where I might read about this kind of problem and how to fix it and has anyone
else had this happen too?
Thank you,
Martha

Easiest thing to do is contact AppleCare and get it replaced. They'll send you a replacement and then you return the bad one. No waiting or fuss. Usually arrives within a couple of days.

Why isn't my wired Mighty Mouse scrolling down?
