Google has not been my friend searching for a fix to this - other than finding out that a bunch of people ask Microsoft forums & all they get back is 'oh what type of computer is it'? (The issue is in the browser not the computer). When you are using Edge (default browser in 10), and you are using the mousepad & then go to move over to use the scroll bar, it will increase your screen size. You then have to manually set it back. Then a few minutes later - same issue. Is there any way to force disable the zoom that keeps occurring? It just did it again to me, when I went to scroll down & find submit and I had my finger on the mousepad.
