Hi Iulian, IE can only apply one "filter" to an element at any one time and the code that jQuery uses to fade-in something uses up that one opportunity. Therefore, when you apply filter:(opacity=90); in the CSS problems occur when JS wants to also apply filter to that element. That is my understanding of these IE issues anyway. My advice is to simply remove that line of CSS so IE degrades gracefully until it can handle opacity in less hack-ridden way.
