Can dragDrop know the source chunk?

[Ken Ray]

David,

You *can* trap it in dragStart... I created two fields, one with this
script:

global gChunk
on dragStart
  put the selectedChunk into gChunk
  pass dragStart
end dragStart


and the other with:

global gChunk
on dragDrop
  put gChunk
  pass dragDrop
end dragDrop


I end up getting the selectedChunk in the message box. Perhaps something
else is getting in your way?
