What steps will reproduce the problem? Please attach sample code if you
can.
1. Apply attached patch 'DemoDragHandler.diff' to  
com.allen_sauer.gwt.dnd.demo.client.DemoDragHandler. This will make it so 
attempting to drag 
Widget #5 in Demo 1 will throw a VetoDragException.
2. Run the demo and open Demo 1
3. Click and drag Widget #5, drag the mouse until the pointer is outside of the 
widget

What is the expected output? What do you see instead?
Expected: Dragging Widget #5 will do nothing, but other widgets are draggable 
after attempting 
to drag Widget #5
Actual: You cannot drag any of the widgets until you do a mouseUp over Widget #5

Do you have a workaround?
Apply attached patch 'MouseDragHandler.diff" to 
com.allen_sauer.gwt.dnd.client.MouseDragHandler
