[WSG] z-index problem

[Gallagher, Robin]

Hi

I've got a 3-column page with footer:

#header {
        position: relative;
        background-color: #33ccff;
        background-image: url(crest_banner1.jpg);
        background-repeat: no-repeat;
        height: 100px;
        border-bottom: 1px solid #fff;
        z-index: 190;
        }

#header_text {  
        font-size: 400%;
        margin-left: 80px;
        }

#more   {
        font-size: 90%;
        }

#leftcol {
        clear: both;
        float: left;
        width: 30%;
        margin-left: 0px;
        margin-top: 0px;
        margin-right: 10px;
        background-color: #fff;
        background-image: url(background.jpg);
        background-repeat: no-repeat;
        padding: 2em 10px 20px 10px;
        border-right: 1px solid #0a57a4;
        }

#rightcol {
        position: absolute;
        left: 68%;
        top: 130px;
        width: 30%;
        padding-left: 10px;
        padding-right: -10px;
        margin-top: -2px;
        margin-left: 10px;
        z-index: 3;
        padding: 2em 10px 10px 10px;
        background-color: #fff;
        background-image: url(background.jpg);
        background-repeat: no-repeat;
        border-left: 1px solid #0a57a4;
        }

#leftmenu {
        font-size: 80%;
        }
        
#content {
        margin: 0px 32% 0px 32%;
        padding: 10px 10px 10px 10px;
        color: #000;
        background-color: #fff;
        z-index: 100;
        }

#hnav {
        position: relative;
        background-color: #ffa615;
        background-image: url(bluebox.gif);
        background-repeat: repeat-y;
        color: #fff;
        height:1.6em;
        border-bottom: 1px solid #fff;
        z-index: 200;
        }
        
#footer {
        z-index: 4;
        clear: both;
        width: 100%;
        margin: -1px 0 0 0;
        text-align: center;
        font-family: Verdana;
        font-size: 11px;
        padding: 3px;
        border-top: 1px solid #333;
        border-bottom: 1px solid #333;
        color: #fff;
        background-color: #0a57a4;
        background-image: url(bar.jpg);
        background-repeat: no-repeat;
        }

which works ok, excepting that the rightcol sometimes goes over the top of the 
footer (ie when text is resized larger), despite having a lower z-index. Any 
thoughts why this is happening and how to fix it?

TIA
