Windows 8 Pro 64bit ¦ Version 6.2.9200 Build 9200
Problem:
While typing text, the cursor is jumping, which leads to unreadable text and/or deletion of text (Word 2013, Outlook 2013, Excel 2013, Chrome, ...).
I try not to touch the trackpad while typing.

Run System Update to make sure you have the latest Synaptics driver.
Then follow these instructions, except turn PalmCheck UP instead of down.

Jumping cursor as I type

I just recieved my new PB today and havne't been able to use it because of the jumping cursor problem when I am trying to type. When I type my hands are elevated at about 1/2 an inch over the track pad. As I type in both Entourage and Word, my mouse will suddenly register a click and move my cursor to where ever my mouse is sitting, usually a few lines above. sometimes it will select the text to above the line and as I continue to type it will over write the content.
I have seen another posting about a similar problem with people clicking the trackpad. I'm not doing that, my hands are no where near the trackpad.
Anyone seen this behavior? Or more importantly, a solution?

This preference has been around for quite a while although the problem you are experiencing surfaced when Apple started making their own trackpad as opposed to buying Synaptics (I that's who they were from).
One option you have which will fix the problem is to attach a mouse. That way you can turn the trackpad off when you have the mouse attached. Otherwise, what you can also do is turn off trackpad clicking. Yes this does force you to use the clicker but will mean that the trackpad alone can't move your cursor.

Jumping cursor messes up typing?

I have noticed that while I am typing that my cursor may jump to a different location so as to cause me to continue typing in the wrong area. I do have one possible solution-- I have noticed that the page up/down buttons are a little close and thought that I may be bumping the key while typing as they are very sensitive.
I have also seen some erratic behavior with the mouse pad occasionally.
Two questions:
Anyone else having these issues and have you found the solution?
If it is just the bumping into the up page key then is there a way to disable the page up key?

o you think its possible that the track pad is reading my hands as they float over the track pad?
(1" - 3" above it? )
Unlikely. I do not think it is possible.
I have not had a problem since doing the switch but I also have not done a lot of typing either so I am still keeping this post open for now.
I have noticed though that now my cursor gets stuck when I try to move it. I now have to sort of run my finger all over the trackpad to get it going. I think this is due to the one setting for "ignore accidental trackpad input".
It is a real pain by itself, lot to mention the jumping cursor problem.
I love Mac-- I hate Mac support.

T420 problem: Cursor jumping around

Hello everyone, I have a new T420s. Whenever I type a text the cursor jumps around which is very annoying. I have already deactivated the touchpad but the problem persists. What can I do to solve it?
Many thanks,
Torsten

You can turn the trackpoint (stick) off on the T420, it does not seem to allow you to turn the trackpoint and touchpad off at the same time through the UltraNav utility, but it might be possible in the BIOS.

A11-ST3500 :: missing Win login dialog, jumping cursor, delayed file saves

Greetings. Lifelong HP user. Decided to try Toshiba for employee and myself.
Went online and configured Tecra A-11SP3500. Have had nothing but problems. Mainly after it goes to sleep mode, when I try to wake it, I get the background screen with no log in. Must take the battery out in order to reboot.
As has happened twice as I have been typing this so far, the cursor jumps all over the screen.
Both issues are common with both laptops purchased.
Then there is the lag when I attempt to save anything. "Save As" screen pops up, "Not Responding" pops to the top of the screen and 10-15 seconds later it will save.
I am running very little on the machine. Office 2010 and little else.
I have contacted support thrice. Had trouble locating model # as all that is on or in the unit is A-11 but all listings have a suffix afterward. Finally got support on third call, to help locate the support page and a model number via the s/n.
Reloaded OS once after initial install. Upgraded bios and drivers. All to no avail. Support seems to know or care very little about the product or problem.
Any suggestions are welcomed. I am a very disappointed customer and wish I had stuck with HP.

Hi Ross,
Have you tried calling back support (800-457-7777) after reloading the OS and updating the BIOS and drivers? If not, I recommend giving that a shot, along with looking for assistance from this user community.
If the Toshiba tech you speak with can't resolve the issue then they should either escalate your call to a higher-skilled agent or refer you to a repair center, if they determine that there is a hardware failure. Send me a Private Message with your name, phone number, and laptop's serial number if your call does not result in a suitable resolution.
I understand your disappointment but am renaming the Subject of this thread to something that describes the problems you're reporting, since that is much more likely to lead to finding help here in the forums.

Jumping cursor while typing, how can I stop it?

My cursor keeps jumping around when I type message. Whats wrong with my mac and how can I fix it? Please help!
All the keys are fine and everything else runing good, but whenever I type messages or a long message it just keeps jumping back like one word or two and I keep having to click back where I left off. It usually happens when I push the space bar. I'm not sure what the problem is. Should I just take it to the mac store?

Your keys could be dirty especially if you make it a habit of eating & drinking while using your computer. A can of compressed air or a brushed vacuum hose will get the dirt out from under the keys.

Windows 7 hang/freezes | jumping cursor

For no appear reason my win7 will hang and freezes, ctrl/alt/del won't help and the only way is to force shut down on the power button.
My usual programs running are: MS office, safari, Chrome, Window Explorer.
Another issue is, as I am typing this, the cursor will starts to jump randomly... I'm not anywhere near the touchpad, and it has already occurred 3 times while typing this message.
It's relatively a new macbook pro, Windows7 with bootcamp 3.2 installed.

I haven't gotten through the installation yet. I get a disk read error before the install is complete. Then it freezes and Cntrl, Alt, Delete doesn't work. After trying for at least five minutes I can turn off the computer and go back to the Mac OS. This after trying all kinds of things including downloading new versions of Boot Camp and firmware that my computer rejected. Anyone have any suggestions, or I will have to call Microsoft. I notice sometimes the dvds don't work without a phone call to punch in a code.

Jumping cursor

Can anyone help me please? My cursor goes all over the place when I try to type. Typing e-mails, typing in this post, typing in the google question bar, everything.
If I don't watch it constantly (and I am no touch typist) I find I have typed over something I have previously typed. it keeps jumping all over the place.
I also have trouble with the pointer. It sticks a lot and is difficult to control.
What can I do to cure it?

I joined purely because I have been experiencing the self same problem with my curser. Before I try this 'fix' of turning off my touch pad, how do I turn it on again please, as I don't have an external mouse.

Jump cursor

I did a search and didn't find anything on this subject. My cursor jumps around. I can be searching with the cursor. Click on some link. When the page finishes loading. My cursor jumps to another place on the screen. Any ideas? really got worse after installing Leopard.
Thanks, Dave.

Is it a wireless mouse or wired? What kind of surface are you running it on? Some (especially older) optical mice can be touchy about the surface they are working on. Mirrors and glass are a definite no-no. Woodgrain can present problems. So too can very smooth, featureless, colorless surfaces. You may need a mouse pad.

Update 17.1.1.A.0.402 - has ruined the keyboard.....jumping cursor

Now when I'm typing an email, the cursor continualy 'jumps' (from the 'body' of the email) to the address.
I was just composing a short note & it did this at-least 6 times - this is now awful.
I was happy with this tablet - it is now un-useable.......
SONY please rectify this ASAP.

Just re-installed SwiftKey & it behaves with this.
It seems only the Xparia keyboard is broken - well done SONY........

Apple's user forum jumps cursor

As I type in these message fields on Apple's own forum, Safari will arbitrarily make my cursor jump up a few lines as I'm typing. I don't know what's causing it. I'm typing along and then BAM the cursor jumps to the end of a line above and I am typing up there instead of where I was.
Anyone else getting this behavior?
Thanks

Go step by step and test.
1. Restart
2. Shut down the computer.
    Clean the trackpad with moist not wet microfiber cloth.
    System Preferences > Point & Click
    Try turning off three finger dragging and then turning it on after testing.
3. Is there any Bluetooth device nearby with failing batteries? If so, replace the batteries.
   4. Reset PRAM:   http://support.apple.com/kb/PH14222
5. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
6. Close all windows and quit all applications.
    Click the spotlight -the magnifying glass icon- in the menu bar. Enter Disk utility in the box.
     Select Disk Utility from the drop down. When the Disk utility window opens up,
     select Macintosh HD, then First Aid.
     Click Repair Disk Permissions button.
     Ignore the time remaining estimate.
     Last 1 minute may take longer.

Jumping On-Screen Cursor

Dear community,
I am run OS X (10.4.10) on my G4 400MHz PowerMac and have been trying to tackle a problem with the on screen cursor because it is always jumping around the screen, a lot of the time jumping to the hot corners and hence exposing my desktop, or sometimes simply trying to move in the opposite direction to which I am trying to move the mouse and hence ending up that the cursor just does not move at all.
Do you know a way that I can possibly fix this problem - it has been getting steadily worse over the last few weeks and it really is quite annoying!
As always, your help as much appreciated - Cheers.

Hi Guys,
It is actually me who has the problem with the mouse, I just didn't realise that I was logged in as the wrong person when I was writing the question last night!
In answer to your question Bee, I am currently using a Kensington ValuMouse. I was using the standard Apple USB Optical Mouse and thought that the jumping cursor may have been due a malfunctioning mouse. I have tried several different mice but they all present the same problem.
I am using a fairly plain Mouse Pad. I am running another computer (with a separate mouse) from my desk and use the same Mouse Pad for both mice. I do not have any trouble with the other computer so I am not sure if it is the Pad that is giving me trouble - I will try another just in case.
If none of those work I will try reinstalling the drivers and will get back to you if that manages to solve the problem!
Thank for all your help - much appreciated.

Text cursor jumps back several words or lines when delete key is struck

Have read many posts about jumping cursors, apparently both on screen and in text. This problem relates strickly to text mode, and can occur in iMail, iChat, doing a Google Search in Safari, or literally anywhere I am entering text. The incident most often occurs when I use the delete key to eliminate a duplicate letter. For instance i typed "billl" instead of "bill" and when I struck delete to eliminate the duplicated "l" the cursor jumped back 10 spaces.   My fingers did not go near the track pad, or magic mouse. Interesting enough when I typed "billl" in the previous line the cursor jumped to the capital M in iMail.
I just tried to double space to start this line, and the cursor jumped and deleted the " at the beginning of the first "billl"
Sorry to be long winded, but since this is occurring in several apps, it would appear to be an operating system problem, or maybe something with the mouse driver. Does anybody have any clues?
Thanks,
Wes

Have not found a solution, have spoken to Apple folks they thought it was the mouse, but after going through 2 new mouses I have temporarily given up.   Recented upgraded to Mountain Lion also, and still have the same problem
I have gotten in the habit of just watching what I am typing more closely so things don't get screwed up so much.   Now interesting enough, I have no problem so far when typing in this box.   I am still trying to collect clues as to where the problem lies. It does not seem to be consistent. Most problem is in email, but sometimes it occurs in Pages too   as well as in Messenger.
