Right now as it is, if I log in as a customer, and I have a previous log-in remembered, the remembered log-in stays in effect, and the customer's account does not log-in because the previous one is still logged in.

Any suggestions?
You would have to initiae the logoff procedure. I'm not too sure, but I believe there's a notifier hook to initiate the logoff procedure with the Automatic Login. If I'm not mistaken, you could trigger the hook somewhere in the Log in as customer header. Are you familiar with coding?
