Problem corrected itself.Installed Kubuntu 14.04. Easy installation, however after supplying the required data in Kmail, I selected Get Mail. The inbox indicates 22 emails downloaded, however the entire screen shows, at the top, The Kmail Icon and the word Kmail. Below that is the welcome screen. When I select 'Inbox', the emails are not revealed. The image on screen remains the Kmail Icon and the Kmail greeting. What am I missing?
