Trackpad behaving erraticaly

It seems the trackpad on PowerBook G4 is not working quite correctly. Contact around the edges seem to move the cursor quickly, but the center and bottom moves the cursor much more slowly. Am I seeing things?

you could look into a trackpad preferences to make adjustments.
it is possible for the trackpad to wear off over time, if it is not working properly and adjustments/cleaning does not help, usually the whole top case would have to be replaced.

Why doesn't the rotate gesture on my trackpad behave as it used to for switching between tabs when it works the same with all other programs besides Firefox?

Why doesn't the rotate gesture on my trackpad behave as it used to for switching between tabs when it works the same with all other programs besides Firefox?
I changed the about:config to make the rotate gesture move between tabs, and it worked great for well over a year. Now it behaves erratically as described here:
https://bugzilla.mozilla.org/show_bug.cgi?id=877598
It used to be very controllable to move one tab over, now it is erratic and moves quickly and to unexpected tabs regardless of how slow I do the rotate gesture. This is the main reason I use Firefox over Chrome and I would like to continue to do so unless there is no fix to this.

Just set the browser.gesture.twist.threshold to something around 15-25.

My Magic Trackpad behaves as if the left 'button' is being randomly pressed. What gives?

I've got a Macbook Pro running OS X Lion. I use a Magic Trackpad for my daily work and have found that it has performed wonderfully...until today. About an hour into my morning work, my Magic Trackpad behaves as if I'm randomly pressing the lower left corner to click. I've cleaned it with a microfiber cloth and tried disconnecting and reconnecting the unit. No joy. I tried turning to the 'Tap to Click' functionality from System Preferences > Trackpad. Once I do this, I cannot click anywhere. Even using the trackpad built into the laptop.
Since I normally physically click on the lower left corner every day, I'm wondering if I've somehow worn out the device already? As best as I can tell, however, there is nothing wrong physically with the device.
Any suggestions before I take this thing to the Apple Geniuses?

The local Mac Genius confirmed my suspicions that it's wear and tear on the device. Simply put, the Magic Trackpad isn't designed to take a lot of physical 'abuse' via physical left clicks. Suggested fix was purchasing a new unit and using the 'Tap to Click' functionality located in the Trackpad Point & Click settings under System Preferences.

Trackpad behaves oddly when firewire is used

All of a sudden my trackpad start to behave oddly when I have a firewire device connected. Specifically a MOTU Ultralite mk3 hybrid paired with a MOTU ultralite mk3 firewire. The problem started yesterday when I launch Logic Pro X. a minutes after the trackpad starts to be unresponsive and the pointer moving in wrong direction or jumping.
I tried to reset the PRAM with no luck. Even worst, when I tried to boot the macbook pro after rebooting the system freezes on the logo screen when the firewire port is used with that device. when I disconnect the firewire port the problem totally goes away.

RE: Guiness (nee Harpoon) Solution
Perhaps it is now time for the Harpoon solution (aka the Guinness solution in the mid and far west)
for those not in the know:
1. turn everything off.
2. unplug firewire cables
3. unplug power cords
4. get up from well worn chair
5. walk to refrigerator
6. open refrigerator
7. remove bottle of Harpoon (Guinness, local micro brew, etc)
8. pop cap
9. pour into glass ( you AREN'T going to drink it from a bottle, are you?)
10. sip responsibly. enjoy the moment. think pure thoughts
11. return to kitchen. If less than 15 minutes has elapsed, have another. Otherwise, retrurn to edit room.
12. Plug everything back together
12. fire up external monitors, VTR, external hard drives & computer in that order.
Does it work now? If yes, congratulate your self. If not, oh well, but at least you are in a much better frame of mind to begin some serious troubleshooting.

Trackpad behave odd after upgrading to Snow Leopard

I've just installed the excellent Snow Leopard and the update to 10.6.1. Without changing anything else on my much loved mac the trackpad has got a strange behavior of accepting single klick only on its own terms.
Sometimes a slight touch result in a klick and sometimes I have to klick several times before its recognized as a klick. Irritating and annoying.
Seen in other posts that the track pad seems to be somewhat difficult to master and cause several problems with Snow Leopard. Any ideas would be helpful. Maybe I'd better down grade to regular Leopard again (but no that's what the PC guys does).
BR /C

A hardy welcome to you. PC comment misleading. Only some go back and for specific reasons not inability to fix their problems. I think your problem is deeper than lack of practice with the trackpad under SL. You could try re-installing SL over SL (via simple upgrade, of course).

How long should a battery last on a macbook air and why is my trackpad behaving strangely?

My macbook air is only 6 months old, but I have noticed the trackpad reacting strangely. Sometimes when I click once it clicks twice for me, and sometimes I only have to hover my fingers over the trackpad and it clicks for me. Is this the signal of the battery needing replacement already or something else? My nearest Apple store is 2 hours drive away so I don't want to go there if I don't have to, so advice would be gratefully received

Lindymac
I have been told that I should 1. drain it low at least once a month, and if it is 2. kept plugged in it will have a shorter life,
Yeah, whoever told you that told you the wrong thing.
You NEVER want to do a full discharge
Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
*Contrary to some myths out there, there is protection circuitry in your macbook and therefore you cannot 'overcharge' it when plugged in and already fully charged
You certainly CAN leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.
*However if you dont plan on using it for a few hours, turn it OFF (plugged in or otherwise), ...*you dont want it both always plugged in AND in sleep mode
LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...
LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to LiPo cells is instances when often the cells are repeatedly drained very low.
*Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
Just use and enjoy your new macbook,
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
and best "tip" is if its near a socket, .....plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"

Mouse & trackpad is not working properly in flash games

I thought the problem was with my mouse. But even my trackpad behaves weird.
When I try to click this game (http://jayisgames.com/games/red-remover-player-pack-2/) or any other games before, single clicking any clickable spots in the flash game works. But in that game, I could single click on "Play Game," "Ok." "the red face," "Play" & box 1. But from that on, I must double click to make anything work. It's not that game that requires double clicks. I've been playing it for a long time, all only single clicks. From there on, I single click on a red box, nothing happens. Then I click on another spot, that previous click happens.
Not just on that flash game, I've tried many others ones, all gave me this click delaying problem.
When I try to click on spot A, nothing happen. Then I click on spot B, the click on spot A happens. So I must double click on everything to work.
I realize I couldn't single click on anything to work on any flash websites (sample:http://www.mono-1.com/monoface/main.html). Clicking once just highlights the link, must click again to make it work.
Please try out that game to see what I'm talking about. I'm not promoting anything here. I got a serious mouse problem.
Thanks.

Trackpad Bug in 10.9 (click is delayed, results in strange behavior)

Hi everybody,
Since updating my Macbook (5,1 late 2008, SSD, 8GB-RAM) to 10.9 Mavericks my trackpad behaves buggy in the following way:
When I press down the trackpad with one finger the corresponding "reaction" seems to be delayed (not every but most of the time).
This results in real annoying behavior when you try to select some text with the cursor, or try to move a tab or file etc.
Sometimes, also "tracking" is lost while selecting or drag&drop operation thus resulting in unselected lines of text, or files or tabs lost on drag.
I updated from 10.6.8 (Snow Leopard) and the described bug has never occurred before the update.
Is this a known bug? Does Apple work on it for 10.9.1? Any suggestions?
Thanks.

Thanks four your reply.
I already looked at the metalink doc. It lists 4 bugs introduced in 10.2.0.5, but none of them seems related to my problem. Did I overlook something?
Regards,
Henk

Very Erratic Trackpad Behavior - Heat?

The trackpad on my one-year-old MBPro has started exhibiting extremely erratic and intermittent behavior:
• Taps react as control-clicks
• Cursor jumps and becomes impossible to control
• Drags and scrolls behave unpredictably
The trackpad becomes impossible to use. Eventually, as now, everything returns to normal. I'm very experienced in the proper use of the trackpad, and am familiar with the 'phantom fingers' phenomenon, so no need to advise against keeping extra fingers and hands away from the trackpad.
This behavior has even occurred when standing well away from the computer: after fighting to control the cursor and restart the computer via the Apple menu, I left the room and returned to see a contextual menu of the Activity Monitor (set to auto-launch at restart) being self-activated.
I'm starting to guess that this is related to heat issues. In support of this theory, the following:
- This behavior was first seen a few months ago when I traveled to the south of France where it was quite warm, and the computer had been playing video for some time. The computer was indeed rather warm.
- Now it's summertime and the ambient temperature is warmer (though here in the Netherlands, it's not exactly tropical). The last two occurrences of this behavior (yesterday and today) have been hot sunny days. After allowing the computer to cool, the trackpad behaves as normal.
Others have reported strange trackpad behavior, but they seem to believe it is caused by defective or damaged hardware, or else user-error. It is often suggested they check their trackpad System Preferences. This post which supports my theory that this is indeed heat-related problem, also remarks that the problem is more likely when the battery is charging.
Can anyone offer advice, explanation or supporting arguments?
Thanks

Try using your laptop without the battery installed (ie remove the battery and run the laptop from the mains supply only), and see if that cures the problem.
If it does, then you have a warped battery casing, and will need to replace the battery.
The battery sits directly over the trackpad circuitry, so that if the battery casing warps, it presses against the trackpad circuitry and causes it to act as though you have pressed it.
If that doesn't cure the problem, then you probably need to replace the trackpad, itself.

Cursor behaving erratically

Since a few days back I am having a issue with my cursor. The little arrow seems to have life of its own. The cursor jumps across de screens sometimes even performing clicks.
I have a Macbook Pro Retina with Maverick 10.9.1 installed.
How can I fix this issue?
Thank you,
D

Hello Diegooriani,
It sounds like you are getting some erratic cursor behaviour on your MacBook Pro. I recommend taking a look at the following information from the article named:
Portables and Magic Trackpad: Jumpy or erratic trackpad operation
http://support.apple.com/kb/ts1449
The Apple Magic Trackpad and built-in trackpads on Apple portable computers work on a principle called coupling capacitance. As your finger moves over the surface, the trackpad evaluates the change in capacitance between two layers of measurement electrodes built into the surface of the trackpad and translates that to cursor movement.
Verify only one part of your finger is touching the pad. You cannot use a pen or other object--the trackpad is designed to work only with your finger. Also confirm that you are not resting your wrist on or very close to the pad. The trackpad may interpret this as your finger touching it and make the cursor move in that direction. If you suspect either of these is causing the cursor's behavior, try raising your wrist in the air and touch the pad with only the tip of your finger. If the symptom goes away then, you know that one of the above is the cause, and you should adjust the position of your wrist or finger.
If you have sweaty hands or if moisture collects on the pad, this may also confuse the trackpad. Wiping off the trackpad with a cloth or tissue usually fixes this issue. If the issue goes away when a piece of paper is put between the finger and trackpad you may want to consider purchasing a Teflon applique to fit over the pad to prevent the moisture from having direct contact with the trackpad. Before installing the Teflon applique, confirm the trackpad is clean and dry. You can use a mild glass cleaner sprayed onto the cloth, not onto the trackpad itself to clean the trackpad.
Oil or lotion can also cause the same issue. Do not use hand lotion, or consider purchasing a Teflon pad to protect the trackpad. Before installing the Teflon pad, confirm the trackpad is clean and dry.
Jewelry may also cause interference. Try removing rings or bracelets and see whether the jumpy or erratic behavior disappears.
Apple has had some reports of this behavior related to power supplies made by a third party company. If you are using one of these power adapters, unplug it and try running from the Apple battery to see how the trackpad behaves. Also try using the Apple AC adapter instead of the third-party AC adapter. If the trackpad behaves normally while running from the Apple battery or adapter, there is most likely an issue with your third-party adapter.
Thank you for using Apple Support Communities.
Take care,
Sterling

My Magic Trackpad won't stop clicking EVERYTHING!

I bought a Magic Trackpad around last year in May, and suddenly it started clicking everything! It randomly settles down, but when I maneuver the mouse around the screen it starts clicking and highlighting everything. Has that happened to anyone else? I'm not sure what's wrong with it. Can it be fixed or is it now completely useless and do I have to throw about $70 away and get a new one?

A quick fix for you to try;
If you have an iPhone in the room, turn it off.
My trackpad was going mental clicking by itself, I turned off my iPhone (4) and trackpad behaves normally.
Been watching a movie now for an hour and no 'magic' clicks.
This just seems FAR too ridiculous to be the problem, but would be interesting if a few of you guys could give it a try also.

Scroll is broken on month view in Calendar

i can no longer scroll to next or previous month with trackpad in Calendar's month view. when i swipe two fingers up or down (or left/right) just nothing happens. is it intentional stupidity to force me to click left/right arrow buttons on top-right?

Hello there, konkere.
The following Knowledge Base article offers some great recommendations for issues with erratic behavior with the Trackpad on our MacBook Pro:
Trackpad or Magic Trackpad is jumpy or erratic
Follow these steps and recommendations to resolve the issue.
Be sure only one part of your finger is touching the trackpad and that you are not resting your wrist on or very close to the pad. The trackpad may interpret this as your finger touching it and make the cursor move in that direction.
If you're using the Magic Trackpad, be sure the batteries are fully charged.
Moisture collecting on the trackpad can also cause this issue. Wiping off the trackpad with a cloth or tissue usually fixes this. If the issue goes away when a piece of paper is put between the finger and trackpad you may want to consider purchasing a Teflon applique to fit over the pad to prevent the moisture from having direct contact with the trackpad. Before installing the Teflon applique, confirm the trackpad is clean and dry. You can use a mild glass cleaner sprayed onto the cloth (not onto the trackpad itself) to clean the trackpad. Note that oil or lotion can also cause the same issue.
Jewelry may also cause interference. Try removing rings or bracelets and see whether the jumpy or erratic behavior disappears.
Apple has had some reports of this behavior on Mac notebooks being used with power supplies made by a third-party company. If you are using one of these power adapters, unplug it and try running from the Apple battery to see how the trackpad behaves correctly. Also, try using the Apple AC adapter instead of the third-party AC adapter. If the trackpad behaves normally while running from the battery, there is most likely an issue with your adapter or outlet.
If none of the above resolve the issue, try to rule-out software not created by Apple as a cause. To do so, start in Safe Mode.
Magic Trackpad can act erratically when there is interference. See Wi-Fi and Bluetooth: Potential sources of wireless interference for more information.

Attributes passed in HTTP Header but not received in my application!! Help

Hi all,
I am running Sun Directory Server 5.2, Access Manager 7.0 and Policy Agent 2.1 on an IBM Websphere 5.0 web server.
I am using a "shared" authorization model where I am using the AM only for the authentication part.
The way my application is structured, it is supposed to receive certain attributes from the LDAP and then based on these attributes the application does the authorization.
I am trying to receive the values using
request.getHeader("app_variable1").
However, sometimes the attribute picks the value and at other times it becomes null. It is not working consistently.
I have done the necessary changes required in the amAgent.properties file:
1. I have disabled the agent realm in websphere
2. com.sun.am.policy.amFilter.mode = SSO_ONLY
com.sun.am.policy.agents.do_sso_only = true
3. com.sun.am.policy.amFilter.ldapattribute.mode = HEADER
4.
com.sun.am.policy.amFilter.ldapattribute.map[attribute1]=app_variable1
com.sun.am.policy.amFilter.ldapattribute.map[attribute2]=app_variable2
// where attribute1 is an existing attribute in the LDAP
// where app_variable1 is the variable name which is mapped to the ldap attribute for getting the value in my application
// request.getHeader("app_variable1")
The values appear on the index.jsp page when I getHeader() there, but as soon as I forward to the Servlet which does the authorization, it behaves erraticaly - sometimes system.out.log has a "null" value for the attributes and at other times it gets the values and works fine.
Can somebody PLEASE tell me what is going on? I have tried out everything but just cant break through this one.
ANY help would be really appreciated....
Thanks...
Note: I also tried using cookies for passing values, and they work absolutely fine - consistently, but cookies are disabled in many browsers and hence carry a disadvantage. I HAVE to use headers - which are not giving the value consistently
--------

Bernhard:
Actually the headers are not set to null. I have an intermediate index.jsp page which is the first page that is redirected to by the AM - it is this page which calls my LoginServlet.
The value appears consistently on this index.jsp page but after it is forwarded to the LoginServlet it starts behaving inconsistently. I check the system.out log in my websphere /logs folder and that tells me that LoginServlet does not consistenly get these values from the header.
The wierd part is that if I use cookies or attributes, it works perfectly - each time every time. However, only in the case of headers (which is the method i am required to do) it behaves inconsistently.
ANY feedback/help on this would be really appreciated bern.. thanks..

BED is Getting Double in MIGO while creating of RG23D entry

Hello,
While we have procuring some material to DEPOT directly from vendor. As per government rule we are maintaining the ZMRP and ZABT condition types in Pricing procedure
In Pricing procedure
10 ZMRP Step from 0 to 0
20 ZABT Step from 10 to 0
30 Sub total from 10 to 20
ZED% is calculted from this step "Amount for ED Calculation"
means the BED is calculted on MRP-38%Abartment charge.
means BED=ZMRP-ZABT%*14%
We have assigned Subtotal 5 against the ZED% condition in our pricing
procedure.We understand that subtotal 5 should not be used for non
deductible BED as it is used only for Deductible BED.But we are
procuring the same material in manufacturing plant as well therefore we
are using Subtotal 5 in the pricing procedure.
If we use ED setoff tax code then BED is taking correct value from JMO1
condition
In DEPOT the ZED% 14% from Pricing procedure and JMO2 from Tax procedure it is adding in MIGO Excise tab while creating the RG23D entry .why it is behaving like this
Please let us know Why it is behaving erraticaly in DEPOT?
Regards
Mahesh Naik

Please check ur setting of maintainexsice defaults.
BED condition type should be properly maintained.
regards,
Sujit
