Comment 24 for bug 1715479

Everything is about the same. I have an updated BIOS, but the real question is:
can you replicate my issue. The issue isn't that the touchpad is enabled or disabled. I can't click or use it to scroll at all, aka: disabled.

My issue is that when I out 3 fingers on the touchpad then go click on something. Sometimes it works, sometimes it doesn't, and sometimes it acts as if I just grabbed whatever it is that I clicked on.

I replicate this by clicking on a scroll bar of a browser or a terminal window while I have 3 finger placed on the disabled trackpad.

You may ask: why in the world would someone ever put 3 fingers on a trackpad then try to click? Well, I have larger hands and often times, part of my hand rests on the trackpad and REALLY screws up things.

Please let me know if you can replicate this on your t460p.
