How do I keep the next message from opening?

I am using the free version. Using the layout that puts the messages to the right. 
When I open the program the first message opens and if I delete a message the next message opens. 

If I delete an email I need the next email Not to open. 
It would also be nice that when I open the program if the first email didn’t open. 

I see messages in this forum from 3 years ago saying that this will be implemented, but can’t figure out how to do it. 

Thank you.
