  It was posted several times to this list but so far no reply seen.
                                                      
  The problem is (according Microsoft):

" ....
Note  SIGINT is not supported for any Win32 application including
Windows NT and Windows 95. When a CTRL+C interrupt occurs, Win32
operating systems generate a new thread to specifically handle that
interrupt. This can cause a single-thread application such as UNIX, to
become multithreaded, resulting in unexpected behavior. 
                      ================================ !!!!
  .... "

  The worst thing is (by Microsoft again):

" TerminateThread is a dangerous function that should only be used in 
the most extreme cases".


  One workaround for this is present with "Microsoft System 
Journal", March, 96. (See source code on Web http://www.msj.com)
