 Brand new installation of WordPress (4.7.4), the only thing installed on
 the site are the default themes, Genesis (current) and Lifestyle Pro
 (StudioPress child theme). Problem DOES happen with default Twenty-xx
 themes. NO plugins installed or activated.

 When I go to Appearance > Customize, Site Identity > Select Image (to add
 favicon), the media Select Files page appears. Pressing Select Files would
 not open file selector - nothing happened.

 Going to Media, then clicking the Add New button at the TOP of the Media
 Library page: click Select files button, again nothing happens.

 However, going to Media > Add New (NOT using the button at the top of
 Media Library page), pressing Select Files - DOES work and the select
 files pop-up works.

 Problem does not happen in other browsers. Current version of Chrome is
 installed. In reading a ton of other reports I came across a suggestion to
 go into Chrome settings, under Advanced settings, and UNCHECK the box
 under Privacy for "Protect you and your device from dangerous sites."
 Unchecking that box DID resolve the issue.

 After the problem resolved, I re-checked that security setting box, tested
 again, and the issue did return. For now I am leaving the privacy setting
 unchecked but I don't want to leave that setting unchecked permanently.

 Worth mentioning that I have over 50 WordPress websites that I manage,
 NONE of the others that I tested on had this issue. Just this brand new
 installation.
