When I click on a web link in an email, eMClient automatically takes me to that web page as soon as I have clicked on the link.
I would prefer it to open web pages in the background so that I can continue going though my emails without interruption, and then I can turn to the web pages later, when I choose.
Clicking url weblinks in any email client will normally open a browser window in front of your email client. That’s the nature of web browsers in the various OS opening when you click url links.
