The contacts column

Good day

The contacts column can not be clicked any more. Nothing happens when I click on it. It does not open the contact register.
Thanks for your feedback and best regards

Hello Herbert,
what version of eM Client does this happen with? Can you copy the full number in Menu>Help>About?
Do you have any Contacts folders set up? Does anything change when you enable Local Folders? (Menu>Tools>Settings>General>General)

Hi Olivia
Thanks for your prompt feedback and comment. Found the solution in the meantime with your input…
Best regards
