Thanks James!!! This problem has been driving me nuts for some time now. My touchpad would freeze for a little less than a second after I click anything. Seems like nothing but it's REALLY irritating and to me it makes the touchpad unusable.
I have a W510 with 64-bit Win7 Pro with a Core i7 and 8GB RAM. It turns out that the only thing that was turned on for me (under Smart Check Settings) was "Scrolling Region Filtering". When I turned that off and hit apply, the problem went away immediately.
Thank you for your posting... It boggles my mind why that article doesn't come up when I search the KB for "touchpad freeze". Come-on Lenovo!
Try this and see if it helps.

We experienced similar problems on our ThinkPad edge 14" (2010 pre-SandyBridge Core i3 model) after the Ultranav driver was updated via Windows Update a couple of days ago to 126.96.36.199. The issue was resolved by removing the Lenovo driver and replacing it with the Synaptics generic driver (as discussed earlier in the thread).
Is there a link to download the previous version of the Ultranav driver, to see if this is a driver issue?

I just bought the Edge 13' with AMD processor and installed Win 7 (64bit). I installed all the drivers with the Think Vantage System Update. Also for the ThinkPad UltraNav Pointing Device. (188.8.131.52 from 17.02.2011, and I tried another version from 31.03.2011)
My problem is that my touchpad, my trackpoint and all the keys up and below the touchpad were and are not working at all. (before and after any driver installation). If I connect an external mouse with USB it works without problems.
I also recognized that there is no UltraNav Tab in my system control (although the drivers are installed). There are only 3 tabs (general, drivers and details)
I already tried to install the Synaptics drivers, but it didn't help either.
Do you have any other suggestions? Or do I need to return it to my Lenovo dealer?
Thanks for your support.

i would like to know what touchpad the Thinkpad E520 has, Alps or Synaptics. I am asking because i just bought a Dell Vostro with an Alps touchpad and i am thinking of returning it because the touchpad is just horrible. The touchpad in my macbook (it should be an Synaptics one) is way better compared to Alps.
So before i buy the E520 i would really like to know what TP it has.

I just got my Thinkpad Edge 15 yesterday but now the touchpad & trackpoint don't work anymore. I had no problems in the beginning but around the time I was updating windows I noticed that the touchpad "froze" a few times, and a little while later it stopped working altogether.
I have updated the drivers, uninstalled them and installed them again with no luck. I have also noticed that I can't find the devices in my device manager. If you exclude my usb mouse, there are no mouse devices in the list.
I also tested booting ubuntu from a usb stick but the touchpad didn't work there either.
