T430s two-finger scroll occasionally causes page to 'jump'

My problem occurs sporadically while using two-finger scroll to read documents online. I'll scroll up or down a little bit and the page will jump as if I had pressed pagedown or pageup (sometimes it jumps even further). I'm currently using Two-Finger Scroll and Chromium Wheel Smooth Scroller (a Chrome extension that provides smooth scrolling similar to Mac's inertial scrolling), and I've disabled SynTPEnh.exe since it interferes with GTK+ apps. I've updated my touchpad drivers and fiddled with the settings to no avail. Has anyone else had this problem, and if so, were you able to fix it?
Many thanks in advance to anyone who can share some insight regarding this issue.

I experience this sometimes, it is sporadic and doesn't happen all the time. I just scroll back to the right place. I use the trackpoint most of the time so this is not a very serious issue to me.

  • T430s Two finger scroll not working reliably

    Hi!
    Sometimes it works, sometimes it takes the skin of my fingers to get two finger scroll working.
    The system update does not see a reason to update the drivers.
    Is there more effective software for the synaptic touchpad to do two finger scroll?

    Hi, theking2
    System Update is a very useful tool, but I find it best to always check for driver updates manually, just in case the updater missed something. The latest version of the Syanptics driver can be found here and may help your issue.
    Hope it helps,

  • T430s two finger scroll

    Hi!
    More often than not two-finger scroll only works after going back and for more that 10 times on the touchpad. I have the latest drivers but two finger scroll is sluggish and unreliable to pick up.
    Are there settings to improve two finger scrolling?

    Hi, theking2
    I did some research on your issue and I found this thread that has users with a similar issue. One of the users, hysy, linked a program called TwoFingerScroll that helped him and many others. You may want to give that a shot.
    Hope it helps,

  • T430s: Old mouse drivers? (two-finger scroll broken)

    Hi all,
       I just used the lenovo update manager to update my mouse driver to version 16.2.19.2 (latest) for my T430s with Win 7. Previously I had been using the two-finger scroll all the time and have really been enjoying this feature. However, the new driver has been giving me some unwanted behavior - instead of scrolling only on two fingers, now it scrolls with one finger about half the time.
    I've double checked that I'm not accidentally touching the pad with another finger. I one-finger edge scrolling disabled, as I have found this unreliable anyway. I can get back to reliable one-finger movement by un-checking the two-finger scroll from the advanced ultra-nav options in mouse settings. However, re-enabling this still gives the unwanted one finger scrolling for a touch anywhere on the pad.
    So unless anyone has any better ideas, I'd figure I would roll back to the older driver. Unfortunately, the lenovo update manager has no history of the old driver, nor does windows device manager. And the driver listed on the lenovo site here, is the same version as the one I'm currently running. So.... anyone have the link to the old driver or any other ideas?
    Thanks!
    [Edited to avoid wall-of-text]
    Solved!
    Go to Solution.

    Okay, I've tried multiple un-install / re-install cycles. I've removed the ultra-nav and synaptics files after uninstalling the driver from device manager and add-remove programs (you have to do both it seems). And a fresh re-install of both, together and individually.
    The problem still persists.
    After checking with other solutions on the forums, I gave a third-party program "two-finger scroll" a try (http://code.google.com/p/two-finger-scroll/) and it is working much better. I can't devote any more time to this problem, and this solution seems to be excellent.

  • Two finger scrolling does not work ONLY on Firefox

    This just started today, suddenly my two finger scrolling doesn't work but only when I'm in Firefox, offline and on Safari and Chrome it's fine. Restarting Firefox only fixes it for a few minutes, then it stops working again. All of the suggestions I've found that I've tried haven't worked, please if anyone could help and also break it down fairly easily, I'd really appreciate it.

    The same issue happens on Firefox 35.0 running in safe mode, Mavericks 10.9.5, both with Magic Mouse and normal standard mouse...
    It's unbeliaveble this issue is going on since more than one year ago, I can find people complaining about it since December 2013!
    Oh, one more thing: I don't have a two finger swipe configuration, I have single finger swipe, so the actual problem is about scrolling the page in itself (considering I've tested it with a normal standard mouse as well....).

  • No Right-Click or Two-Finger Scroll in Boot Camp

    I have had an odd problem. It looks like others are seeing this too, but I wanted to record my observations.
    Recently I have begun to notice that after booting into Windows 7 Pro (64-bit), I will briefly have two-finger right-click and two-finger scroll capabilities, but then these just go away. I have tried deleting the trackpad drivers that came with Boot Camp 3.2 per what I have seen on other threads, but that makes no difference. I also downloaded and reinstalled Boot Camp 3.2/64-bit; again, no difference.
    If anyone has any ideas, I would be happy to entertain them. Thanks!

    Ok this situation appears resolved on my MBPro so here is my handy guide.
    1) Visit Apples Product Support Page and Download this AppleBCUpdate Windows Executable
    http://support.apple.com/kb/DL874
    a) Download AppleBCUpdate.exe
    2) Visit RarLabs and Download a Shiny New Binarry of WinRAR (Demo/ShareWare)
    a) http://rarlabs.com/download.htm
    b) Be sure to get the Latest WinRAR 64x Version
    3) Visit your AppleBCUpdate.exe download location and Extract the Internal Driver Files (NOTE: This APP Will NOT Execute on a Windows 7 x64 Machine simply use WinRAR to UNARCHIVE)
    a) Right-Click AppleBCUpdate.exe, Select Extract Files Here
    b) Navigate to the New Foldier Created by WinRAR's Unarchive of AppleBCUpdate.exe (P.S. It should be named 'AppleBCUpdate')
    c) Locate AppleMultiTouchTrackPadInstaller64.exe
    * Right-Click this program and also Extract Files Here (that is use WinRAR to unarchive)
    d) Navigate to 'AppleMultiTouchTrackPadInstaller64'
    * See the Lovely Driver Files??? :B
    4) Perform a Manual Install of the AppleMTP64 (This is your working x64 Multi-Touch TrackPad Driver)
    a) Visit StartMenu->Computer
    b) (Right-Click) Select 'Properties'
    c) Select 'Device Manager'
    d) Select the 'Human Interface Devices" Tab
    * Target -> "Apple Multitouch" driver
    * Note: This Driver may say something similar like: "Apple Touchpad"
    * Tip: Make Sure it is NOT: Apple Keyboard, Mouse, IR Receiver, Wireless Mouse, Bluetooth Controll Receiver, or any of those other 'HID-Compliant Devices'
    * Once you have Determined Your Driver the -FUN- Begins
    5) Select 'Update Driver'
    a) Use the "Browse My Computer For Software" option (Manditory)
    b) Select "Let Me Pick a List of Drivers for My Software" (Or whatever it says)
    c) Select "Have Disk" Button and Point to the Location of "AppleMTP64"
    * This driver means "Apple Multi Touch Pad 64" NOTE: Do not use AppleMTM64 as that is a Mouse Driver (..and using that driver is an erronius procedure )
    d) Once the Driver is Loaded "Apple Multitouch" should be listed as a compatable Driver.
    * This is the Updated Version of the Best Working Driver
    6) Reboot and Enjoy
    ATTN: I belive this problem is cause by two Factors
    1) Apple did not build an Executable for Updating Windows 7 64bit with ApplePCUpdate 1.1
    * You have to extract all the special files to get it to work
    2) Window 7 'as-cool-as-it-might-be' does not always utalize the 'Best' Driver for your system, as so prevailantly obvious for their systems.
    ALSO:
    Visit: http://support.apple.com/kb/DL1066 to Update your MultiTouch TrackPad for MacOSX (it may help)
    Above all I have tested this workaround a little bit and it appears to be working pretty good. ("p)

  • 10.5.2: Two finger scrolling makes computer hang unrecoverably

    I installed 10.5.2 on my MacBook Pro as soon as it became available a couple of weeks ago. Since then the computer hangs unrecoverably, on average, probably a couple of times per day. Is there anyone else out there who is encountering the same problem? Very frustrating since any on-going work that I have not saved will probably be lost!! (although this actually did not happen in practice yet).
    Here are some details:
    What happens exactly?
    The cursor freezes and can no longer be moved. And the computer does not respond to any other command that I know of - except an ungraceful hardware shutdown (i.e. pressing the power button for three seconds). So that's the only escape.
    When does it happen?
    So-far it has probably only happened while using Safari. And probably only while scrolling - by moving two fingers on the trackpad. But the reason why it happens then might be linked to the fact that this is an operation that I do a lot.
    Suspicion:
    I suspect that the hanging is related to two finger scrolling rather than Safari since I have noticed another strange behaviour while scrolling; Once in a while the scrolling does not quite work as it should and I am taken very quickly (as in momentarily) to another part of the page where I am scrolling. These "scroll jumps" (that are quite confusing since I lose my orientation on the page and have to go search for the place where I was reading) happen when I press my fingers very lightly towards the trackpad as in barely touching at all. (I can intentionally reproduce the behaviour.) It is my hunch that the two phenomena have the same cause - so that the light touching sometimes causes a hang rather than a "scroll jump".
    Any help towards solving this problem would be very appreciated! It's not very Mac like that the computer "crashes" a couple of times per day...

    As it turns out the reset of the PRAM did not help. My computer just hang again a moment ago in the same way. And I was forced to do power-off/on reboot again as usual. This time I had unsaved work. But thankfully my Mac was bright enough to save this(!) (My unsaved textedit file emerged effortlessly as soon as I opened the textedit application. And my unsaved e-mail draft could be found in the "drafts" folder exactly as I was hoping.)
    I will go ahead now and try cleaning up my user and system cache files as suggested to me here:

  • Two finger scroll problem in Preview

    When viewing a pdf with over 200 pages in Preview, for example a pdf book, two fringer scroll stops functioning periodically. In order to get it working again you have to click on the destop and then click back onto preview to get two finger scroll to work agian. Is this a limitation of the Preview app? This does not seem to be a problem with smaller pdfs.

    You aren't the only one having this problem.

  • Two Finger Scroll Reversed in Modern Apps

    Hello, I have a new Thinkpad Yoga and for some reason two finger scrolling in modern apps is fixed to reversed scrolling (scrolling down moves the page up and vice versa).  Both horizontal and vertical scrolling are affected. 
    I have the latest Ultranav drivers and I unclicked "reverse scrolling" from the options.  Desktop Apps scroll normally.  Also, when I use the edge scroll it works as expected on both desktop and modern apps.
    I'm thinking that there are separate entries in the registry for scrolling in modern apps or something like that...
    Thanks!

    Solved!
    Go to Solution.

    Hi, thanks for the help.  Unfortunately I have already tried that.
    I figured out it has something to do with how the latest UltraNav driver treats the touchpad in the Win8 modern environment.  It simulates a touch screen when using two fingers.  I installed the generic Synaptics driver which solved the problem but created a new one.  Namely, it does not turn off the touchpad when using the Yoga in tablet or stand modes. 
    Another solution was to go into the registry and disable the TouchInjectionAction Key.  This helped in some apps but others wouldn't recognize scrolling at all.
    I'm honestly at wits end...

  • Two finger scroll problem

    Hello. Today i bought a MacBok Pro and i've got a problem with the gestures. Every single gesture is working fine (one, three, four fingers and two finger click) EXCEPT the two finger scroll. I just doesn't work at all. Can somebody help?

    I have exactly the same problem on my Macbook. Even the other two-finger gestures like turning pictures around in iPhoto or zooming in are working - it´s ONLY the scrolling that doesn´t work EVER. This is a pity, as it´s the most useful gesture imho.
    Anyone else having problems or any solutions in sight?
    Thank you very much in advance.
    Oh, and if it is useful for the solution: I´m also having the click&responsiveness trackpad problems that are causing so much trouble these days.

  • I am using Mac running OS X Mavericks (10.9.1) and Firefox 26. Two finger scroll down is not working all of a sudden only with Firefox.

    Hardware : Macbook Pro
    Operating System : OS X Mavericks v10.9.1
    Browser : Firefox v26.0
    All of a sudden, two finger scrolls doesn't work. Thats only when I am within Firefox Window. Everywhere it just works great. I got NO scroll bars at the edges of browser(Firefox) too. No way of proper browsing other than switching to Safari.
    Request to fix this asap.
    Thanks.

    I'm having the same problem but what I found was the scrolling on my iMac was it works until you try and swipe to go back a page. Then the only solution is the quit the program and restart it.
    Spec is an Apple magic track Pad on my iMac with OS X 10.9.
    I'm currently using FireFox v25 but the same issue is in v27.0.1.

  • Satellite C50-B-14D - Two finger scroll is not working

    I have had my laptop for about 6 months now and am generally happy with it. However, the two finger scroll has stopped working (it was working fine when I got it and for a while after). I know it's not essential, but it makes such a difference for the work I end up having to do, which often involves copying and pasting etc, and I really miss it!
    I've read many threads saying that you should go to Control Panel, click on Mouse and go to device settings. However when I get to that point, my Mouse box just says "buttons; pointers; pointer options; hardware" and there is no "device settings" panel along the top. What can I do? I also can't find the synaptics driver anywhere to uninstall it, as some other people have suggested.

    Obviously this additional touchpad feature isn’t available because the touchpad driver isn’t installed.
    I recommend you to visit the Toshiba EU driver page and to download the touchpad driver for this notebook model.
    I’m not quite sure what touchpad module this notebook supports (Synaptics or ELAN) but I think you could try to check both drivers.
    If one would not work, check the other one…
    After that you should see the additional tab within control panel -> mouse

  • Two finger scrolling when a PDF file is inside a frame

    It seems two finger scrolling does not work for PDFs inside a frame. An example of this is the Wiley Inter Science webpage. Any suggestions?

    This has come up a number of times in the forum. Some web sites employ either proprietary or Flash enabled GUI objects on their pages. These simply will not work in the ipad's Safari. There really is no workaround. I've contacted the web site's webmaster whenever I run across one of these. I would think that with the number of iPad users going into millions, web sites would want to change such behavior. They need to know.
