      Description



      Name: mc57594 Date: 01/29/97


      MouseDrag events are not being delivered if the mouse moves
      outside the bounding window and should do so (otherwise how can one do
      drag and drop?). Compile the following 2 classes, run, and start a drag
      within the pink label. Then continue the drag until it moves outside of
      the label's bounds. You will see in the console window that the drag
      event stop comming once the boundary is crossed. This is not correct,
      the events should continue to arrive (with location relative the
      component where the drag began) until a mouse release event occurs
      regardless of mouse position.
