Well, I'll be damned. I was having the same scrolling problem but pushing down really hard seems to have fixed it!

Same for me here. Just press down the knob a few times and it normally works again. Though I hate it - just awful quality.
 
Oh dear! Some people really do like making a mountain out of a molehill!!

The ball will, over time, obviously pick up dirt and grease from your fingers. The easy way ( advocated by Apple ) to clean it is to lay a lint-free cloth (which has been dampened with a little water) on the work surface, turn the mouse over and whilst pressing down, roll the mouse fairly vigorously over the damp surface. Leave the mouse for a while to dry out and it should be as good as new. I personally prefer to sparingly use Isopropyl Alcohol (used for cleanib recording heads etc).

Hope this helps.
 
i've had my new imac for 3 weeks and noe the mouse won't scroll down. this is ********. I've had nothing but hassles with this computer anyway. I misss the apple of old when quality mattered. No matter what i do to the moouse it wont scroll down again so i believe the bearings on the bottom side are shot:mad:
 
Pressing hard on the scroll ball solves the scrolling-down-problem for me too!
Thanx for the tip!

I hope the problem won't come back though :p
 
pushing it really works!

Thanks for the advice!
My scroll didnt work downwards, but i pressed it really hard and moved it around and now it works fine.
Thanks!
 
Same here

I've had the same problem, several times in fact. The scroll goes out every couple of days.

I thinking of just buying a completely different mouse brand because I'm hearing more and more about all the problems the (not so) Mighty Mouse gives users.


I recently developed a scrolling problem with my Mighty Mouse. It started to only vertical scroll in one direction. I reinstalled the software and it did not help. So, I called Apple tech support. While waiting on the line, I decided to press quite hard on the scroll button and try to scroll. That cured the problem, after that it only required the normal light touch to work properly. I do not know what was the cause of the problem, maybe dust(?), in any event it is working fine now.
 
I'm sorry if I'm repeating what someone else said (didn't bother reading previous posts) but here is what works for me 100%.

I have these small Alcohol Swabs I bought at the Pharmacy and when the scroll don't work I:
- take a swab
- make it a little dryer by tapping it on paper (but keep the swab a little moist)
- roll it over the scroll wheel in every direction.

This works everytime and on more than one mouse. Try it out.
 
Happened on first day I had my iMac

Although it's probably quite valid to point out that the MM scrolling problem can occur with the buildup of dirt over time, that doesn't explain why I first experienced it within hours of setting up my brand new iMac.

Although the "push hard" option does seem to work, I also find that restarting the computer can also fix the problem. That must mean there's more than a dirt issue here, surely? My friend who got his iMac on the same day in another part of the country experienced the exact same thing with his Mighty Mouse within hours of his setting up his computer. So something isn't right...

Cheers

My friend had the same problem with his MM. He bought a new mac and just used the new mouse though.
 
How long did all yours take to start malfuctioning. I have had mine for 2 months and not a single complaint... well right clicking only works about 60 percent of the time, but I've gotten so used to it I don't even noticed my constant right clicking to hopefully get a response...
 
Read the entire thread and was skeptical about Apple's suggested cleaning method (I'm sure I was way past the "pressing down really hard on the ball..." method :))...I was eager and ready to jump directly into the "let's take the MM apart method" (which BTW is a great tutorial in itself as to how to take the mouse apart for any other reason you might have).

Decided to give Apple's method a try and surprisingly it worked! Now, don't expect the dirt to dislodge after a few rubs, I had to continously rub for about 3 minutes for it to start responding then a couple more minutes did the job.

Still, I think Apple should work on a redesign of the trackball (being that a lot of analogies have been used in this thread, mine would go like this: it's like purchasing a top of the line automobile and having to step out of the car every so often to get the windshield wipers dislodge so they can keep working)...otherwise a great mouse -productivity wise-.
 
I'll like to add to my previous post that, in my personal opinion and experience, the procedure indicated by Apple to clean the mouse should be a scheduled maintenance rather than a proceedure employed only once the scroll ball stops working.

At the office I'm having all five mouses "cleaned" once every week now and so far they perform flawlessly...
 
Mighty Mouse Scrolling Problem Resolved

I too had a similar problem. Suddenly my mouse would only scroll vertically and in an upward direction. Pressing firmly on the ball while scrolling resolved the problem. However, it was necessary for me to change the function of the scroll ball from "dashboard" to "button 3". Once I temporarly made the change and pressed firmly on the scroll ball all was back in working order. Thanks for figuring it out.
 
Pressing hard fixed it for me

I had the same problem occur with my wireless mm and I pressed down very hard on the ball and it worked.:)

It happened to my MM BT after about 3 months. I went to the Apple shop where I bought it (Eplehuset Oslo) and they replaced it no questions asked. I had my new one 4 weeks and it has happened to this one as well. Can´t scroll up.
I tried to push hard on the ball, but no success.
Guess I should give Apple´s method a try. Surprised they gave me a replacement instead of cleaning it though
 
Different scrolling problem...

I used to have the same scrolling problem (only scrolling up worked) but during the move to a new place I guess any debris got knocked out. I still have the same problem, but it's not a hardware issue. I can only scroll up w/ the MM on certain ads on treehugger.com that have embedded video. As I scroll down the page, it stops at that ad, and I have to move the pointer elswhere before it will continue to scroll down. What's up (no pun intended) with that?
 
a nice solution without breaking anything!

Hello folks!

I did this:

1- I pour 3 drops of WD-40 in the gap of the little track ball and turn the mighty mouse upside down for avoiding contact of the liquid with the inner electronics.
2- I rubbed it very hard with a clean cloth and all the grease and dirt disolved by the WD-40 began to emerge.
3- Applied pressurized air to the gap... and that's it!

The dashboard or the function you have by pressing the little ball won't work for 2 or 3 days while the WD-40 dries. After that you will have a fully functional MM without surgery.

Hope this can help!!!! :)

Everyone who has a Mighty Mouse has this problem it's a design flaw, go to the Razer Store and buy a good mouse not the rubbish Apple is pushing onto consumers.....

I think Apple products are great however the Mighty Mouse is complete junk I have gone through 4 of the dam things (to Apple's credit they did replace them for me) ALL of them with the same problem from only a few weeks use.

The scroll on the Mighty Mouse is flaw I really do hope Apple address this issue next Mouse update :apple:

Had mine for a year and still haven't had a problem, and I eat all the time while eating my might mouse. It's really weird that it hasn't happen to me yet. Knock on wood.

Seems to be the case of people either love of have the MM.

My MM stopped scrolling too, bought a new one plugged it in and everything works again. Hate to admit it but put old one in box and returned it (CompUSA). Did not want to deal with warentee for a MM.
 
Might Mouse scrolling problems

I am a realitive newbie to Mac's
But even on a PC scroll mouse where you have to tickle the mouse's ball's the same problem occur's.
It's a moving part which accumulates skin particles, dust and dirt.
Yes, we are all dirty, no matter how strict your cleanliness regime.
The solution is so simple from my experience, unplug the mouse, thouroughly clean the ball vigorously in every direction with a baby wipe, then dry it using an absorbent soft paper kitchen towel.
Leave it for five minutes to dry out and hey presto!!! it works like it should in every direction.
The problem is a recuring one, but short of taking the thing to bits to clear out dead skin, a regular cleaning program seems the best solution.
