Jatos experiments that work perfect on my mac freeze for other (windows?) users
I have a puzzling problem and am hoping to find help here in finding a solution as I have time pressure to get this experiment to work for students. My issue might be related to yesterdays' about black screen freezing, but it in my case it seems specific to some users (so far it seems to be specific to windows users).
I programmed two OS web experiments on my mac, and the two of them run perfectly both in Open Sesame, in the external browser as launched from Open Sesame. For myself as well as the other mac user in my house the experiments on JATOS (via a general multiple link) work perfect as well. I tried Chrome, firefox, etc.
However, for my colleague and a couple of students who are windows users the two JATOS experiments, accessed via the same link, crash (seemingly every time around a similar point in time). There simply suddenly is a black screen (and no error message, also not in the browser console) after around 6 blocks of trials in one experiment (around trial 90-100) and around trial 50 of the first block in the other. For both experiments the freezing occurs not only when using an up-to-date Chrome browser and also when using an Edge browser.
In trying to solve the issue I already tried:
- Changing my OS version from the latest release 3.3.5 back to 3.3.0 (which I successfully used for JATOS experiments before).
- Changing the back-end from Legacy to PsychoPy.
- To log only a selected, small number of variables.
- Asking my colleague with a windows pc to export the experiment as a JATOS study from his computer, and upload it on JATOS.
Neither of these things changed the freezing behaviour.
Issues with the server seem highly unlikely, non of my colleagues have issues and when my colleague and I run an experiment simultaneously from a mac vs. windows pc it only crashes for the user on windows.
I would be happy to share the link to the experiment and code in PM if that is helpful.
