// The effect of including this script is that a global property with the
// name "windowState" is assigned an object that has 4 methods that will
// tell you what you need to know about the viewport/window:-

	var viewPortWidth = windowState.getWidth();
	var viewPortHeight = windowState.getHeight();
	var horizontalScroll = windowState.getScrollX();
	var verticalScroll = windowState.getScrollY();

// That script covers a very wide range of browsers (all that I have
// sufficient details of) but, like any JavaScript, it is possible that it
// will encounter a browser so unusual that it just will not work. In that
// event it defaults to returning zero for all values. It is always
// possible that the real (and accurately reported) value for the viewport
// dimensions are zero so you might want to test for that possibility and
// just place the DIV at the page's 0,0 co-ordinates as a fall-back
// position.

// The horizontal position of the DIV would be calculated as:-

	var hPos = Math.round(horizontalScroll+((viewPortWidth-divWidth)/2));

// And vertical as:-

	var vPos = Math.round(verticalScroll+((viewPortHeight-divHeight)/2));

// - but either value may come out less than zero in which case it should
// probably be defaulted to zero:-

	hPos = (hPos < 0)?0:hPos;
	vPos = (vPos < 0)?0:vPos;
	
	return [hPos, vPos];
