Opera y float

[jesusjj]

Una cosa más, eliminando el panel, hace lo mismo, de forma totalmente aleatoria muestra el postit, con lo que en principio lo achaco definitivamente a algo del CSS:

Código:

html {
	margin: 0px;
	padding: 0px;
}

body {
	background: #ccc url('../../img/back.jpg') repeat-x;
	text-align: center;
	margin: 0px;
	padding: 0px;

	font-size: 10pt;

}

	margin-top: 20px;
}

	background: #ccc;
}

	font-style: italic;
	font-weight: normal;
