JavaScript mouseUp event ignored when mouse is released during drag

$j(divID).bind('dragstart', function (event) { event.preventDefault() });

Thanks all

90% of the time, this is because the dragged element is in front of the element with the mouseup event listener, so the parent element underneath never gets the event.

Usually, this can be fixed by using addEventListener as opposed to the inline form of the event. Another way to fix this is to give the dragged element an eventListener for when the mouse is released. Also, you can have a div that is put in front of all other elements whenever an element starts to drag (via the zIndex property).

Edit: I whipped up some proof-of-concept code: http://jsfiddle.net/2BkEM/5/
