The documentation was just not updated for Vista/Win7, I see you still didn't scroll down to user comments on your quoted page. > And no excuse for not correcting the current Harbour behavior, IMHO.

Did you test this effect on all possible MS-DOS host environments? F.e. Win9x DOS box, NTVDM on Win7, NTVDM on Vista? DosBox on any operating system? DOSEMU? They may be different, and they probably _are_ different. I see no need to try to hard-wire XP NTVDM specific behavior to our GTs, or to control such XP NTVDM-like behavior to SETCANCEL(). >> but maybe rather it could be the standard GTWIN >> behavior (without any extra setting).

SETCANCEL() controls the interpretation of Ctrl+C, which it does perfectly on all GTs in Harbour.
