Post Lists and Open Link in New Tab functionality

Hi,

We’ve installed (and love) the newspaper theme on our site. We’re currently under construction and testing and have come across a strange issue.

We link to other sites from both pages and posts, and in every case we use the ‘insert a link’ within the WP editor. We select the ‘open in another window/tab’ checkbox, but we are getting mixed results. On pages and some posts, it works as expected. But on other posts, it’s either opening the link both in the same tab as well as another tab (in chrome), or only in the originating page (in safari).

The only thing we can narrow it down to that we’re doing, is the issue seems to pop up when we use “Post Settings>Smartlists”.

Is there something we’re doing wrong or can fix via CSS?

Thank you,

Chris
