Guest sessions are no longer released while the telescope is still travelling to its target. The inactivity timer only advances on commands you issue, so a long slew — up to about four minutes for a full turn in azimuth — looked like an idle visitor and could end the session and stop the telescope part-way there. Time spent slewing no longer counts towards the three-minute inactivity limit; time spent tracking a source still does, so an abandoned telescope is handed back as promptly as before.
