Exiting a program logs me out!

[Jay Maynard]

I'm trying to get the dte editor, which was recently posted to
comp.binaries.ibm.pc, to work on my System V. The author, Douglas Thomson,
included complete source, as well as an I/O module for HP-UX. Unfortunately,
it used the TIOCGETA and TIOCSETA functions and the sgttyb structure, which
aren't supported under vanilla System V. I figured out how to convert them to
termio calls, and got everything to compile.

When I run the program, though, it runs fine until I exit. It then gives me a
shell prompt - and then logs me off.

I'm sure this is something dumb that I'm doing, but I can't for the life of me
figure out what. Anyone out there run into this kind of problem before? If
you have, please drop me a note; I'll summarize if there's interest.

Thanks!
