Felix-

I'm not a Linux guru by any stretch of the imagination, so I'm
cross posting this to the more general Informix news list,
comp.databases.informix. You will have to look for responses there or
subscribe to the informix list (not the same as IDS list) through the
iiug. You would probably do well to subscribe in any case, because a
fair bit of useful information passes through there.

For those who didn't see the original post to IDS list, I'm adding it to
the end.

As to the current issue, my new best guess is that it may have something
to do with the curses or ncurses library, but that's just a wild guess.
