            target = target || e.target || e.srcElement;
            if (target == document.body) {
                return;
            }
            if (resizeW) {
                deltaX = startX – _startX;
                w = $(target).width() + deltaX < minSize ? minSize : $(target).width() + deltaX;
                target.style.width = w + “px”;
                _startX = startX;
            }
            if (resizeH) {
                deltaY = startY – _startY;
                h = $(target).height() + deltaY < minSize ? minSize : $(target).height() + deltaY;
                target.style.height = h + “px”;
                _startY = startY;
            }
            if (e.stopPropagation) {
                e.stopPropagation();
            } else {
                e.cancelBubble = true;
            }
        }
