OK, I have constructed a shell script that simulates SWI-Prolog for this specific case, please download it from: https://www.metalevel.at/ei/simulans.sh Place it in the current directory and change the invocation of Emacs to: emacs -Q ceiled.pl -fn "Bitstream Vera Sans Mono 15" --eval \ "(progn (load \"$PWD/ediprolog.el\") \ (setq ediprolog-program \"$PWD/simulans.sh\"))" Note the setting of ediprolog-program to simulans.sh. I can reproduce the issue with this script. If it does not work for you, please try a different window size, font, or running Emacs in the terminal. Thank you and all the best! Markus
