Using 1.4.4 jQuery

font-family: 'Trebuchet MS', Helvetica, Arial, sans-serif; font-size: 14pt;

IE7 & IE8 same effect

function loop_fade(){
    $('#m_notices_c').animate({opacity:0.1},500,function(){
        $('#m_notices_c').animate({opacity:1},500,loop_fade);
    });
}
$(document).ready(function(){

    loop_fade();

});

This is a Cleartype glitch and the problem is documented nicely at http://blog.bmn.name/2008/03/jquery-fadeinfadeout-ie-cleartype-glitch/

this has to do with ie handling transparent backgrounds with alpha blending.

the easiest solution should be something like

#m_notices_c { background:#fff; }
