Sorry it has taken so long to reply. I am using firefox with version 1.4.2. on inspection I get the following - is this helpful or do you need something else?
<input onclick="var popup=$('datepicker_1e7ccafa46af27428bdf3d2d81c9b28d_calendar');popup.clonePosition('lead_aquired',{setWidth:false,setHeight:false,offsetTop:$('lead_aquired').getHeight()});$('datepicker_1e7ccafa46af27428bdf3d2d81c9b28d_calendar').toggle()" href="javascript:void(0)" id="lead_aquired" label="" name="lead_aquired" value="" placeholder="Field required" onmousemove="if(typeof(Utils_Tooltip__showTip)!='undefined')Utils_Tooltip__showTip(this,event,500)" tip="Example date: 15 Jan 2013" onmouseout="if(typeof(Utils_Tooltip__hideTip)!='undefined')Utils_Tooltip__hideTip()" onmouseup="if(typeof(Utils_Tooltip__hideTip)!='undefined')Utils_Tooltip__hideTip()" type="text">
Thanks
