Fix $check for IE7

Reported by Xandros | February 25th, 2009 @ 06:54 PM | in 2.0 (closed)

There is an issue when using onmouseleave events in IE. If the element has a child

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));

    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.

    The above code is the fix.

    If we return false when related is null or undefined, than if you mouseleave on the html element (or body if your html don't have a padding) the event wont happen.

    Looks like the options from a select doesnt work fine with the mouse(over|out) events.

    Look this shell:

    If you enter the select, click, mouseover the option 4 and mouse out of it nothing is printed, it means the mouseout is not hapening. Looks kinda impossible to solve this issue.

    Do anybody has an idea?
