menu_left+=20;
menuOut_id=setTimeout( "menuOut() ",1);
}
function menuIn()

clearTimeout(menuOut_id)
if(menu_left <=-400)
menu_left-=20;
menuIn_id=setTimeout( "menuIn() ",1);
}
function init()
{
menu = Layer1.style;
menu_left = menu.pixelLeft;
menu_top = menu.pixeltop;
menu_heigth = Layer1.offsetHeight;
menu_width = Layer1.offsetWidth;
menu_left=-400;
Layer1.style.visibility = "visible ";
menu.onmouseover = menuOut;
menu.onmouseout = menuIn;
}
</script>
</head>
<body onload= "init() ">
<div id= "Layer1 ">
<table width= "500 " height= "200 " border= "1 ">
<tr>
<td width= "90% "> </td>
<td width= "10% " bgcolor= "#00FF00 "> </td>
