My mail will not allow me to click on anything. I cannot close it(except force quit). I can move the box around(by the header) but cannot resize it, close it regularly, minimize, let alone open any type of email. I have rebooted several times, and yes I'm connected with plenty of pinging. I have tried to go offline then back on-no good. I think something is shut off at the core. I am open to any and all help. Thanks in advance, Bill.
