In threadnav template, function setWidth() should look like this in all styles
Code:
function setWidth() {
var n=list.innerHTML.match(/<td>|<td class="blank">/gi).length;
var tableWidth=(width)*n;
fetch_object('table').style.width=''+tableWidth+'px';
for(i=0; i<cells.length; i++) {
cells[i].style.width=''+(width)+'px'
}
}
But there are various other differences as well.
