Font editor

Dear Enfold and web people :)

When i use the following command in the quick css:

h1,h4 { font-family: ‘lookmedia-font-1000’;

(With the font defined in custom.css true a face-font code.:

/* General Custom CSS */
@font-face {
    font-family: 'lookmedia-font-1000';
    src: url('lookmedia-font-1000.eot');
    src: url('lookmedia-font-1000.eot?#iefix') format('embedded-opentype'),
         url('lookmedia-font-1000.woff') format('woff'),
         url('lookmedia-font-1000.ttf') format('truetype'),
         url('lookmedia-font-1000.svglookmedia-font-1000') format('svg');
    font-weight: normal;
    font-style: normal;

}

The Advance styling editor stops working. It ignors my H3 setting for examle (font)

Some one got a clue?
