Salve ragazzi ho la seguente pagina:

<script type="text/javascript">
$(document).ready(function() {	

  //Get all the LI from the #tabMenu UL
  $('#tabMenu > li').click(function(){
        
    //remove the selected class from all LI    
    $('#tabMenu > li').removeClass('selected');
    
    //Reassign the LI
    $(this).addClass('selected');
    
    //Hide all the DIV in .boxBody
    $('.boxBody div').slideUp('1500');
    
    //Look for the right DIV in boxBody according to the Navigation UL index, therefore, the arrangement is very important.
    $('.boxBody div:eq(' + $('#tabMenu > li').index(this) + ')').slideToggle('1500');
	
	/* function per l'effetto tooltip */
	$(document).ready(function(){
		$('.title_rel').betterTooltip({speed: 150, delay: 300});
	});
	
	$.(function(){
	$('#boxBody #section #all_releases p.title_rel')
		.css( {backgroundPosition: "0 0"} )
		.mouseover(function(){
			$(this).stop().animate({backgroundPosition:"(0 -250px)"}, {duration:500})
		})
		.mouseout(function(){
			$(this).stop().animate({backgroundPosition:"(0 0)"}, {duration:500})
		})
	});
	/* end function tooltip */
	
    
  }).mouseover(function() {

    //Add and remove class, Personally I dont think this is the right way to do it, anyone please suggest    
    $(this).addClass('mouseover');
    $(this).removeClass('mouseout');   
    
  }).mouseout(function() {
    
    //Add and remove class
    $(this).addClass('mouseout');
    $(this).removeClass('mouseover');    
    
  }); 	
});

Funziona benissimo con firefox, mentre con Chrome e IE, se andate col cursore sulle scritte VYNIL e DIGITAL non esce niente. Potete provare qui:
