}

#menu ul li:hover ul{

display: block;
float:left;
}

#menu ul li ul li a{

font-size:16px;
width: 101px;
}

#menu ul li ul li a:hover{

-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
padding-bottom: 10px;

}

quero colocar o border radius no: #menu ul li ul{}

espero que me deem uma luz, esse internet explorer ferra com tudo...

obrigado
