For me the issue appears to be only with Chrome and apps running under Chrome. If I'm using any of the Microsoft Office 365 applications there is no problem. If I'm using Adobe Lightroom/Photoshop there is no problem. If I'm using Interactive Brokers Trader
Workstation there is no problem. For me the problem only seems to exist with Chrome and browser apps that run under Chrome.
Going forward I'm going to start documenting exactly what I'm doing at the time it occurs to be absolutely sure of what I'm saying. I should also note that for me the problem occurs very infrequently and I can often go for quite some time without an occurrence.
Another thought comes to mind. There is a known problem with the touchpad response sensitivity on the right side of the pad. I'm a pen and touch pad only user and I've learned to keep my touch tapping only on the left side where it always works. (I'm totally
mouse-free!)
Are you sure the problem you're seeing is with the entire touch pad?
