From my inbox I normally highlight any emails I want to send to trash and press the DEL key. This morning when I tried to move these across I got a message advising that if I continue it would remove all files from my trash folder. My server settings are move them to nominated folder - see attached. How can I delete from the inbox and transfer to the trash?

The second problem I encounter is whenever I attempt to log into my Thunderbird account I am directed to go through the "Create an account" process as if I don't have an existing account???
