CSS capriccioso?

[wizard86]

Salve a tutti, da un paio di giorni sto impazzendo dietro a questo problema di visualizzazione







Come vedete su Firefox tutto ok, appena lo apro su IE ho quel problema li, idee?

Ecco il css:

body {	
	background-image: url("../images/body.gif");
	background-position: top left;
	background-repeat: repeat-x;
	text-align: center;
	font-family: Arial, Helvetica, sans-serif;
	font-size: 0.9em;
	margin: 0;
	background-color: #005F8C;
}
.head {
	height: 55px;
	/*background-color:#FFF;*/
	color: #FFF;
}
.contenitrice {
	text-align: left;
	margin-right: auto;
	margin-left: auto;
	width: 790px;
}
.left {
	float:left;
	width:259px;
	height:650px;
	/*background-color:#333;*/
	color:#E5E5E5;
	padding-top:0px;
	/*background-image:url(immagini-ristorante-senigallia/sf-left-bottom.jpg);
	background-repeat:no-repeat;
	background-position:left bottom;*/
}
.right{
	float: left;
	width: 531px;
	height: 256px;
	background-image: url("../images/sf-top-right.jpg");
	background-position: top;
	background-repeat: no-repeat;
}
.inside-right {
	margin-top: 256px;
	background-image: url("../images/bg-orizz-right.gif");
	background-repeat: repeat-y;
	padding: 25px;
	font-size: 13px;
}
.right-photo {
	float: left;
	width: 531px;

	background-position: top;
	background-repeat: no-repeat;
}
.right-dove {
