[solved] css: highlighting td

[brown monkey]

i use this

td{
	cursor: hand;
	width: 200px;
	vertical-align: top;
}
td:hover{
	background: #666666;
}

in IE, cursor is hand if hovered but the background won't change to #666666. in contrary, Mozilla change the background when hovered but the cursor won't... am i missing something? thanx...
