This is flagged with the error message "unrecognized media only". Aside from its widespread use, I see that the W3C candidate recommendation for media queries http://www.w3.org/TR/css3-mediaqueries/ explicitly allows such a construction (see Example IX, prefaced by the comment: "The keyword ‘only’ can also be used to hide style sheets from older user agents. User agents must process media queries starting with ‘only’ as if the ‘only’ keyword was not present.") So it sounds like this message is being issued erroneously. For the record, I selected CSS3 level 3 as the profile. 59289 1 ylafon 2011-10-31 13:30:48 +0000 Fixed, the support for media-queries has been redone form scratch, as a result it solved this bug.
