* {margin:0;padding:0;}/*for demo purposes only, use a proper reset in your final layout*/

html,body { overflow: auto; height:100%; }
body {
    font-size:100%;
    background:#777;
}
#wrapper{

    margin:0 auto;
    background: #FFFFFF;
    border-left:1px solid #000;

}
#header {
    background:#77F;
    border-bottom:1px solid #000;
    height: 70px;
}
#content{/*just to create top padding without tampering with min-height:100% on #inner*/
    padding:10px 0;
    overflow:hidden;/*contain floats*/
}  
    #left-index {
        float:left;
        width:220px;
    }
    #right-index {
        float:right;
        width:180px;
    }

Have you tried setting the overflow at the html element only?

html { overflow:auto }
html, body { height:100% }
