Screen freezes or goes blank for some participants
I am running an experiment with OSWeb where participants have to rate images (30-60 min) and on each trial, 10 responses are logged. This experiment worked fine when we tested it on multiple laptops and browsers (Firefox, Safari), we only excluded Chrome because it was error prone.
The study works for many participants, but some participants are reporting different errors related to the screen freezing in the middle of the experiment or the screen going blank.
What could be the reason that this happens, but only for some participants while it works for others?
