Hi
 
  Set Up : Solaris 2.5.1 , JDK 1.2 FCS build 'K' & 'L'
  When trying DnD between Swing components i am getting the following
exception . This happens immediately after i initiate the drag operation.
  In 'J' build it was working properly.Even in 'K' build DnD between Swing components works well on WIndows-Nt and Windows-95
   
 ( mouse Pressed
 starting drag )
        Exception occurred during event dispatching:
java.awt.dnd.InvalidDnDOperationException: The operation requested cannot be
performed by the DnD system since it is not in the appropriate state
