was not working for me also when I needed that IE 6 conditional comment
but this one good:
HTML Code:
<!--[if IE]>
<link rel="stylesheet" href="ie.css" type="text/css" media="all" />
<![endif]-->
so, if you only want apply something to IE 6, just use the litle IE6 hacks in your ie.css file.
HTML Code:
* html #myID{};
The best way I've found...
