<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Just recently started evaluating jQuery (some great stuff!) as
a replacement for an existing JS framework that has proven to be a
performance/management nightmare (won’t mention any names). <o:p></o:p></span></font>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Now for the task at hand, is there a simple way to access
the “ghost” object created by the Draggable object?  Reason I
ask is that I need to be able to change the style of the ghost object as it
passes over valid (Droppables) and invalid drop areas (everything else). 
I know YUI!’s drag and drop API Allows you access to both its proxy (same
idea as ghost) and linked (the original target) object via function calls but I
can’t seem to find anything in the Droppable code that provides for this.<o:p></o:p></span></font>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Another question I have is regarding programmatically changing
the value of “revert” and/or “fx” properties on the Draggable
object.  Is it possible?  I would like to have the animation fx apply
when a Draggable is dropped on an invalid target as the Draggable returns to its
original position.<o:p></o:p></span></font>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Regards,<o:p></o:p></span></font>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
