	var xPos, yPos, offset, dir;
	dir = "";

	yPos = window.event.offsetY;

if (yPos<offset) dir += "n";
	else if (yPos > el.offsetHeight-offset) dir += "s";
	if (xPos<offset) dir += "w";
	else if (xPos > el.offsetWidth-offset) dir += "e";

return dir;
}

function doDown() {
	var el = getReal(event.srcElement, "className", "resizeMe");

if (el == null) {
		theobject = null;
