No post preview in Chrome

Hi All,
When I hover mouse over post titles I don't see a preview box when using Chrome, but okay in Edge.
Started about 10 days ago, is there something in the settings I'm missing?

What is "Edge"?

I think there must have been a windoze update that fixed Chrome recently... Everything works fine on Linux (Fedora 27 with all updates installed).

Microsoft Edge - web browser.
