Drag&Drop with Multiple sources

Hi,

thanks to Ted Brecht I managed to implement a simple D&D from a
ListPresenter with a single selection onto another object.

Now I'd need some help how to do D&D from the same ListPresenter with
multiple selected objects.

I've managed to switch the ListPresenter's view to "Multiple selection
enhanced ..." and that part works fine (except maybe for a "select all").

But the D&D part doesn't there always seems to be only one
InternalDragDropObject.

I think you may have mutated your list into a MultipleSelectionListBox
(corresponding to ListPresenter.'Multi-selection list box') rather than into a
MultipleSelectionListView (ListPresenter.'Multi-selection enhanced list view').

For some reason, the M.S.L.Box seems to provide only a single object when you
drag from it, whereas a M.S.L.View populates the DragSession's #dragObjects
with all the selected objects, as you'd expect.  I don't know why the M.S.L.Box
suffers from this problem -- it may be a Windows thing since the code looks the
same in both View classes (to a casual glance).
