I don't know the editor you talk about but if it uses CURSES then the 
problem may be inherent in libcurses.a. 

In some versions of CURSES (specifically in early System V), if nodelay() is
set somewhere in your program and not reset before the program exits, an EOF
is sent to the parent process that spawned the program. If the parent process
is the login shell then the user is logged off the system.

The trick is to place a line of code:
	nodelay(stdscr,FALSE);
just before calling endwin() in the exiting stages of your program.

Of course all this assumes the program uses CURSES.
