Every time I open the latest First Step Procedural Modeling Lesson 1 hip file, the Houdini Console will show up and keep displaying empty lines one after another, and I can't turn it off.
did you try hit “ctrl - c” in the python shell? i once had similar problems when i went in fullscreen i got a random debug message popping up. I never found out why but i could stop it by pressing ctrl c in the python shell.
