UPDATE: I noticed that box pops up mainly when I go to the Yahoo Mail Login page, which I have set as my homepage.
OS is Win XP SP3. After a recent windows update, every time I start IE8 I get that box which asks:
"Do you want to view only the webpage content that was delivered securely? This webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the security of the entire webpage."
Under Tools>Internet Options>Security>Custom Level...Display Mixed Content, Prompt is checked. On my Windows VISTA machine this box is also checked but I don't get this annoying message each time I start IE on the VISTA machine.
I'm hesitant to make a change under Display Mixed Content because I don't want to put my system at an unnecessary risk. How can I safely fix this issue?
