If you drag after you have made the last selection (without clicking again) 
then it will work.  If you click again, that will be treated as another 
selection operation.  It differs from the KDE/Qt (and I think Windows) 
equivalent which allows a further click after a multiple selection before it 
treats the click as a reselection operation - I think this is different 
rather than unworkable.

You could probably do what you want by intercepting the button-press-event and 
button-release-event signals.
