Answer 1

replace this class in your css file and everything should be fine:
#navcontainer li:hover ul.children {
top:18px;
background:#edebd7;
color:#724e32;
padding:5px;
position:absolute;
border-left:1px solid #694b0a;
border-right:1px solid #694b0a;
border-bottom:1px solid #694b0a;
white-space:nowrap;
width:160px;
height:auto;
z-index:300;
-moz-border-radius:0 0 5px 5px;
-webkit-border-radius:0 0 5px 5px;
border-radius:0 0 5px 5px;
}
the left:0 propriety was the problem. Nothing else :)
