view only the webpage content that was delivered securely?

[snootalope]

We've got a secure site that we access frequently and always get the "Do you want to view only the webpage content that was delivered securely?" prompt. I've already set the "Display Mixed Content" in the security settings to Enable as that's the posted solution all over the internet. This doesn't work for us though. We're using IE8 (due to other limitations) so going to IE9 isn't an option either. I've set the display mixed content in the Internet, Intranet, and Trusted Zones. Set the site as a trusted site and even lowered the security setting to the absolute lowest. Nothing is working..

Anyone been able to get around this prompt when the Display Mixed Content fix doesn't do it?
