Hi Greg,
thank you for your suggestions, I will this discuss with the other core
developer.
At the moment I have only the idea override the stopPropagation method,
to avoid a copy/past:
_onMouseDown : function(e)
{
var oldStopPropagation = e.stopPropagation;
e.stopPropagation = function() {};
this.base(arguments, e);
e.stopPropagation = oldStopPropagation;
}
Cheers,
Chris
