Hi Jacque,
Sorry, I'm coming a bit late...
I have done such a thing in a project where the user can drag and
drop images, movies, sounds and texts from a palette that displays
their images in order to build a multimedia document. So between two
stacks.
I had a specific stack for this purpose displaying an image created
on-the-fly by taking a snapshot.
This tiny stack was shown at mouseDown, covering exactly the actual
image in the palette and then the user could drag it where he/she
wanted.
A pending message told me where the mouseUp occurred and I acted
accordingly.
I used this method since I wanted the stack to move smoothly to its
starting position if it was not in a "right" place and this feature
made the job much more tricky :-)
As far as I remember, a lot of code, some focus and cross-platform
issues and so on, but a fine result :-)
Best Regards from Paris,
Eric Chatonet.
PS. If you are interested in more details, write me off list.

I have a list field that operates like an index; clicking on a line
causes the stack to display content based on the text of the line.
I also need the field to support drag and drop, so that users can
create their own lists by dragging lines from the index into a
different field in a substack.
I tried setting the dragData on a mousedown in the index field, but
even if I pass mouseDown, the index behaviors no longer function.
The field does not recognize "mouseup" or "selectionchanged" and
nothing happens. Actually, when I try dragging a line, the
selection changes to whatever line the pointer is over. Does anyone
have a trick for making a list field behave in two different ways
-- that is, normal line selection as well as supporting dragging
lines to another field?
