Problem viewing the home Page

When open eM Client can view contacts, tasks, addresses and compose a new mail but cannot figure out jhow to see the opening page on which I can view my e-mails.  Must thave done something stupid, but what? Please help

Hi John,
right-click any of the other section titles. A dropdown menu with all the options should pop up, check Mail to make it visible again.
You can hide or show any of the menu items this way.


Thanks, Olivia, that’s fixed it.
So simple, why couldn’t I figure it out?
