Can't add to contact

I can’t add contacts. Not by right click on address and “add to contacts” and not by the drop down menu “add to contacts”.
The only way I found to work is by entering all the details manually in Menu>Tools>Contacts

Please Help 

I just installed eM Client and had exactly the same problem …

Same issue here…

You cannot add a contact by right-clicking on an email address in the Smart Folder, it must be done in the actual folder (i.e., inbox of actual account).

thanks Jay - was frustrating me no end

As an update to this, there are users out there that CAN add addresses via smart folders and according to eM Client, it should work.  I have submitted a support ticket for this and they continue to investigate.
