Look at the second line of the code: WIDTH !!! should be HEIGHT.

It makes Drag&Drop module not working (tolerance):

function outerHeight(el) {

var $el = $(el), oh = $el.width();

for (var i = 0, props = ['borderTopWidth', 'paddingTop', 'paddingBottom', 'borderBottomWidth']; i < props.length; i++)

oh += num($el, props[i]);

return oh;

}
