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 )
