Bug Description:
  When performing drag-and-drop on a deactivated window,
 the window borders become colored as if it was activated.

Steps to Reproduce (be specific):
  Run the BasicDnD example from the Java Tutorial with
  Java WebStart. Display also another application (e.g. the
 command prompt).
  Then select an item in the Jlist, and start dragging.
  Before dropping, pess ALT-TAB and select the window of the
  other application. It becomes active.
  The mouse, however, if kept on the BasicDnD window shows
  that it is performing drag-and-drop: place it in the JText
  area and release it. The borders of the window become
  darker as if it became active. However, the active window
  is the other one (you can see it typing some characters).
