(from Lighthouse)

There is an issue when using onmouseleave events in IE. If the element has a child SELECT element, when opening this select in IE, if the mouse leaves the element but stays inside the SELECT dropdown (further down for example), the mouseleave event fires even though the mouse is still inside the element.

The problem does not occur on Firefox.

var $check = function(event){
  var related = event.relatedTarget;
  if (related == undefined) return false; // was 'return true'
  if (related === false) return false;
  return ($type(this) != 'document' && related != this && related.prefix != 'xul' && !this.hasChild(related));

don't we use the 'native' mouseenter / mouseleave now, if available, which IE supports since IE 5.5.

right, we need to verify the issue

IE7 is using the native version, and the native version fires as soon you hit the border of the select box, it needs further testing so moving this to 1.6
