On win NT, drag-n-drop text from app1 to app2, dnd works fine, but app1 appears to hang afterwards - you can't drag again from app1. However, if you dnd text from app2 to app1, app1 responses and receives data, then dnd from app1 is resumed to work. The problem happens when no dropTargetContext.dropComplete() is invoked in the target.
  
The test case in: /home/tinasu/ws/Drag-n-Drop/SmallTests/TestText/bug4187912 demonstrates the problem.

=====
Test case is now attached to this bug report.
