I've thought of that. And I have been doing my best to keep my hands off the computer while typing, but old habits (like using a regular keyboard) are hard to brake.

but after your advise I found this to turn the trackpad off when the USB mouse is plug in.

Control Panel -> Hardware and Sound -> Devices and Printers (click mouse) -> Device Setting (tab) -> (check) "Disable internal pointing device when external USB pointing device is attached".

We'll see if it works, or I will need to learn better laptop posture.

Thanks

>>This new to me. A few updates ago, my Windows 10 environment started to assist me by changing the overall font size of the current window I would be typing in. So as I typed, the font siz would change from 12pt to 16pt to 24pt, then go to 12pt to 8pt and so on. I am sure that this is some kind of killer new feature to help the a few with attention problems, but the for the average Joe like me, I find it annoying. Has anyone experienced this, and is there a fix. It does not appear to be isolated to any application, but to any application based on Windows technology.

>>p.s. while typing this, the font changed seven times (eight).
