internet explorer 9 - IE9 standard view no load CSS

Question

I have this problem and maybe I'm not the only..

If I test my website on FF, Chrome, Safari, IE7, IE8 is perfect.

On IE9 (standard view) It doesn't load CSS files. If I switch on Compatibilty view it works fine...

How can I show the CSS on the standard view as well?

Thanks

IE9 is known to reject stylesheets which are not sent using "text/css" MIME type. This is a new security enhancement, but it's catching a few people off guard. Is your CSS file dynamically generated? Make sure its getting passed as 'text/css'.

Another try:: It's not just 'text/css' in the doc that needs to be correct, you need to make sure your local IIS is sending it with the proper headers. "If a style sheet is ignored due to an incorrect MIME-type, your site may fail to render as expected. Text, images, or other features may lack the desired styling. If a style sheet is ignored because it does not bear the correct MIME-type, a notification will be logged in the IE9 F12 Developer Tools console."
