CSS problem i IE7

Någon som kan hjälpa mig se vart felet kan ligga i min CSS fil
Den funkar felfritt i IE6 och i Firefox.

Sidan slutar vissas då texten slutas halva menyn blir dold under det försvunna.

Helt jävla kostig IE7 som ska stöda html standarden.
Sidan är uppbyggt i div.

Så här ser min css ut.

* {
margin: 0;
padding: 0;
