How to delete an email account appearing in login drop box?

I have an old email account that I am tryin to delete. It keeps appearing in the login drop box when I am trying to sign in into a website's members area.





I have try the following which still does NOT work:


(i)delete cookies, history, password using the IE build in function


(ii)disabled auto complete in IE


(iii)Control Panel---%26gt;User accounts---%26gt; Manage my network passwords, then removing the account


(iv)Use Advance Window Care 2 Personal to clean my computer.





Anybody knows how to delete it??? My email account detail must be recorded somewhere in my computer, and not by the website that I am trying to visit since I am also using Anonymizer to hide my IP.

go into the setting of that email and delete it at the source
Reply:you have to get it up on the screen and on the top of the page there's a thing that says delete or click on it and make it highlighted and then press the delete button or backspace. But ya. I think that's how you do it but I'm not positive i would have to see it
