I recently upgraded my laptop to IE8. There was a question in the setup that asked something about whether I wanted to display non-secure content. I unthoughtfully answered no, thinking I could change later if needed. After installation, I started getting a message saying "Do you want to view only the web page content that was delivered securely?" quite often when I am on a secure site. I frequently connect to my office e-mail server to access Exchange e-mail and I get this message every time I open a message. How can I turn off this feature so the message does not display?
