[open] Target stimuli disappearing
About one third of the way through my study the stimuli stops showing up and is replaced by a black square in the middle of the screen. The study continues as normal except that there is no stimuli for the participant to respond to. This continues for the rest of the study. I have tried updating OpenSesame, tried downloading the program again from the original source, and tried checking through the file pool as well as the whole program. I've even tried it on multiple computers. The study works on one other computer, however the rest of them have not been showing the stimuli. Any idea what I could do to continue trying to troubleshoot this? Thanks

Hi,
To be able to help you, we would need a bit more information, because right now it is pretty vague. So can you tell us which operating you tried? Which version of OpenSesame you have already tested. Also, it'd be great, if you could upload your experiment. Otherwise we can't do anything but searching in the dark.
Thanks,
Eduard
Hi!
Thanks so much! I've tried running it on OpenSesame 2.8.2, 2.9.2, and 2.9.4 and none of them have worked. The only one that works I believe is running on 2.8.2 but I haven't tried updating it in fear that it might mess that one up as well. I believe it's running in OpenSesame PsychoPY. Here is the link for the study: https://drive.google.com/file/d/0B7vK8Zq35pY4RjBlbGxqUW82bVU/view?usp=sharing
Hi,
Unfortunately, I can't reproduce the error. I tried the experiment with a 2.8.3 and a 2.9.2 version, and both work like a charm. No clue, what might mess things up in your case.
Sorry,
Eduard
Hi,
I've seen this too. It looks like a memory-corruption problem, and seems to be a bug in PsychoPy. It occurs only rarely and on specific systems, or perhaps under specific circumstances--I'm not sure. At any rate, I would see if you can find some information on this on the PsychoPy mailinglist.
You could try updating PsychoPy, which basically means replacing the
psychopyfolder in OpenSesame by a newer version of PsychoPy (i.e. from the PsychoPy source code). If you do this, or if you learn more about the problem, let us know.Cheers,

Hi Sebastiaan,
Thanks so much for your help. I am getting closer to solving the problem. I tried to replace psychopy in the opensesame folder with a newer version but it said it was not able to install the new one properly. Now I think the program won't run at all until I figure this one out. I am going to try and fix that (or if you have any suggestions about that let me know!) but I will keep you updated. Thanks!
