Hi Alex,

I'm still new to RunRev, so I'm not sure if this is the best way to do it, 
but this is what I did to allow drag-and-drop of images:

   on mouseDown
     repeat while the mouse is down
       move the target to the mouseLoc
     end repeat
   end mouseDown

The thing I thought was nifty was that this code goes in the handler for 
the group that contains the images, so all the images in the group are 
draggable without needing their own mouseDown handlers.

One quibble with this approach would be that if you move the mouse fast the 
object you're dragging tends to lag behind so you have to wait for it to 
"catch up" as you hover over your intended destination.
