Steps to reproduce the problem:
1. Put cursor on word chosen to highlight
2. Tap touchpad
3. Text enlarges or gets smaller; no highlighting of single or successive words.

What is the expected behavior?
1.  Word is highlighted
2.Shift key and down arrow highlights text chosen from first word to last
3. Right click on touchpad to copy chosen text
4.  place cursor where the text is to be copied, etc. 

What went wrong?
Text cannot be copied in NY Times.  Works with all other pages tried except NY Times.
Problem reported various places including NYT.  Some cannot replicate it.
Tried disabling touchscreen; made no difference.
Happens 100% of the time I try.
I'd really not prefer to use IE, but this is reported not to happen with that.

Did this work before? No 

Chrome version: 51.0.2704.103  Channel: n/a
OS Version: 10.0
Flash Version: Shockwave Flash 22.0 r0

Never worked with Win 10 and touch screen or non-touch computer.
Worked with all previous versions of Win and Chrome.
I'm really mystified by reading accounts of those who cannot replicate this and those, like me, for whom it is constant.
