Mozilla released Thunderbird Supernova. You know you are going to have a problem because of the cute name. The SW folks managed to destroy the simplicity of the old version. Nothing works! They moved everything around and worse. This is a class SW geeks nightmare product. They took a great working email reader and turned it into a frustrating and defective piece of software junk!
I guess that is what happens when the new generation firmly believes that whatever they think is right and damn the users.
I went back to an old version and blocked updates! Pity.
