Brad, you are right, it does have to do with the graphics in the page. I turned the security alerts on IE and when it loads the graphics it warns that we're leaving the secure connection and when I choose not to continue the page loads with no graphics but the secure icon shows. This kind of sucks ... does this mean I'm gonna have to specify absolute paths to make sure they get requested using https? ... hmmm, I hope there's a more general solution.
