Thank you, Jan.

I routinely use Chrome; it apparently got bugged. In other browsers this does not happen.

Thank you again,
Alex

Oh, the same happens right on this forum page. The word “Thank” in my initial inquiry is underlined.

Here is a link to the blog.

In the very first sentence the word “rich” is underlined and an ad pops up when the cursor hovers over it.

Thank you for looking into that.
