Hi,
I've been having this problem for a couple of years, but now it's becoming more pressing as I add responsive support to my skin.
If there are @media designations in my skin's LESS or CSS files, then when I view the site on IE9, the @media designations are ignored and everything follows the latest CSS rules even if the @media designations don't apply. On the other hand when I load the pages with ?debug=true, there's no problem and the @media designations are respected.
Can anyone offer suggestions?
Thank you, Eli
