Position:absolute; not working

Question

I'm pretty clueless on what the problem might be, but what works fine here does not here (login with 123/123)

CSS:

#drag {
    width: 700px; 
    height: 400px; 
    border: 1px solid #000;
    margin: 0 auto;
    position:relative; 
}



.inside {
    width: 500px; 
    height: 500px;
}
.drag {
    width: 700px;
    height: 400px;
    background: #333 url('bg.png'); 
}

I've tried to remove the .inside class, and also messed with the html a bit (re-checked the pos:relative part a million times)... with no results. Any idea?

[edit]

@Marcel Korpel : On the second one all islands end up in the upper left corner, despite having pos:absolute, top:x and left:x set

I used FireBug and it says that the #nr0, #nr1, ... divs just have a position:absolute;, but no left or top attribute
