This is caused by a security feature in your browser. We have a security token that prevents hacking or spoofing your account. If someone is logged into DT and then let's the login expire, for example, by closing the window or letting it time-out, the security token sometimes isn't cleared. When you try to log in using a different account, it gives the warning Token Mismatch.
