No no, ;)
I forgot to precise that you have to create the image first
A script like this should works to drag a field:
on dragStart
if (there is not a image "DragField" of this cd) then
lock screen
create image "DragField"
set the visible of it to false
unlock screen
end if
export snapshot from field 1 to image "DragField" as PNG
set the dragImage to the ID of image "DragField"
put (the clickH - the left of me) & comma & (the clickV - the top
of me) into tImageOffset
set the dragImageOffset to tImageOffset
set the dragData["private"] to text of field 1
end dragStart
