Windows Live Mail screen defaults to ‘File’, not ‘Home’

My Live Mail (Win10) all works, but its default page is "File", not "Home"..... also when mailing, "File" instead of "Message". This means continual extra clicks just to use 'bold', 'italic' etc. ..... Is there a way to make it stay on "Home" (and "Message") instead of "File"??
