[Moo] IE bug Drag and Drop, container option

[Romain]

Hi,

I noticed a bug with the Mootools DragandDrop I can't manage to fix
(despite documentation and research) occuring on IE (8).

the option
container: $('container_div') gives an error in IE 8, and not in
Firefox.

Anyone know how to fix this ?
Tks;-),
