------------------------------------------------------------------------------


 PARAMETER:

  <hDrop>      Identifies the internal DROPFILES structure that describes
               dropped files. This handle is passed to the application as
               the first ( wParam )  parameter of the WM_DROPFILES message,
               and it is kept in a windows instanceVar oWnd:hDrop 


 DESCRIPTION:

  This function releases the memory that Windows had allocated to transfer
  the filenames of the dropfiles to the application. It is automatically
  called by FiveWin when the window gets destroyed that had received the 
  dropfiles.
