I have a ThinkPad T530 running Windows 8 Pro X64.
I use two finger scrolling with my touchpad, and often scrolling will stop working for a few seconds, causing the cursor to just move erratically instead of scrolling like it should.
The other issue I have noticed is that the touchpad stops working altogether. Load shouldn't be an issue, but appears to affect the touchpad, even when CPU usage is below 20%. (below are my specs).
Of note, I am running the latest UltraNav driver from Lenovo's website, and it works better than the older versions of the driver.
Has anyone else had this issue? Lenovo has been of no help since February, this problem is getting really annoying, and this has been the first machine I have ever used with touchpad driver issues.

Ultranav driver version '184.108.40.206' from June 20th 2013.
