Hi all, after a relative opens up their inbox and downloads a PDF attachment they save it to desktop. Then they click on the button for return to inbox and instead the verizon webmail logs them out and sends them back to the login screen. I guess this just started after I did a repair install 1 week ago. But all the browser settings seem to be good so I'm not sure what is going. Any insight is much obliged.
