asp:Menu hover makes "Security Information" pop up, how do I fix?

Question

I hover over my menu and a submenu expands, then this bad boy comes accross the screen. Is there something I can do in my website to prevent this?

Answer 1

It looks like you're serving your site over ssl (i.e. https://) but serving some of the content, almost certainly something in the menu - such as an image over http://, hence you're receiving the "mixed mode" warning.

Review the markup for your menu and look for any http:// URLs in the .aspx page (or possibly your codebehind if you build the menu dynamically) where there should be https:// or vice-versa.

Answer 2

Make sure all images or external resources are referenced via https.

Answer 3

Hooray I found a fix.

The problem is in the PopOut_Show function. MS does some weird child frame thing. I deleted it and it all works well!
