Scusa se ti rompo ancora, ma non riesco a fermare la posizione.
Posto il css, sinceramente e' arabo per me non so praticamente niente di CSS.
Ciao e grazie ancora.

codice:
#ajax_tooltipObj{
	z-index:100;
	position:absolute;
	left:100px;
	top:0px;
	text-align:left;
}
#ajax_tooltipObj div{
	position:absolute;
	left:100px;
	top:0px;
}

/* If you don't want the arrow - Just set the width of this div to 1 or something like that and drop the background selectors from the CSS below */

#ajax_tooltipObj .ajax_tooltip_arrow{	/* Left div for the small arrow */
	background-image:url('../images/arrow.gif');
	width:520px;
	position:absolute;
	left:100px;
	top:0px;
	background-repeat:no-repeat;
	background-position:center left;
	z-index:100;
	height:160px;
}

#ajax_tooltipObj .ajax_tooltip_content{
	border:2px solid #317082;	/* Border width */
	left:18px;	/* Same as border thickness */
	top:0px;
	position:absolute;
	width:550px;	/* Width of tooltip content */
	height:400px;	/* Height of tooltip content */
	background-color:#FFF;	/* Background color */
	padding:5px;	/* Space between border and content */
	font-size:0.8em;	/* Font size of content */
	overflow:auto;	/* Hide overflow content */
	z-index:100;
}
