| Audio Skipping in Simultaneous Audio Presentation and Recording |

I've been collecting data in a study that simultaneously collects audio using
and presents audio using
. Things seem to be working well overall, but I happened to notice that for at least one participant, the audio stimulus seems to skip in several trials -- in this case the stimulus is also picked up in the audio recording, and I noticed that small sections of the audio stimulus repeated.
My best guess is that this is an issue with doing simultaneous audio output and input that is outside the scope of the SSG, but thought I'd check if anyone else has noticed audio skipping in other studies?
Before diving in to deep, I thought I'd also just check if there are known issues with using audio (which I think uses a standard js audio object) and the background_audio recorder (which I think is implemented here)?
Thanks FF team for putting together this great system!! I've been incredibly impressed with how flexible it has been!

| Timing out |

Hello,
the studies on FindingFive (EU-server) seem to be unavailable. The trouble started around 10 pm (Berlin/Amsterdam time) yesterday evening.
FindingFive will let me log in and out. Yesterday evening I was able to see an overview of my studies and open them, but then it timed out when I tried to look at the materials. A bit later, it wouldn't open at all. Today, it is opening again, but it won't load the overview of the studies available for participation, and neither my own study list. Resource files and help pages are available though.
Currently I have no active studies, and am collaborating on three inactive studies. So far, my collaborators have not been complaining about the same problem. I have tried logging out, logging in, restarting the browser etc., but it doesn't seem to do the trick.
Sometimes, an error message will appear:
DataTables warning: table id=all-experiments - Ajax error. For more information about this error, please see http://datatables.net/tn/7
I would be very grateful for any recommendation, best, Anna

| Retry study after dropping out |

I am currently running sessions with the option to allow past participants turned off, but the option to allow past 'dropouts' to retry turned on. However, I've heard from participants that they haven't been able to retry the study. Specifically, I think participants are opening the study on one device, switching to another device, and attempting to reopen.
It may be that participants simply aren't actually closing the page on the first device, which would be a whole other issue. However, before starting to investigate those options, I thought I'd check if there are other common issues with implementing the retry options or any suggestions for things to check here?
Thanks!

| Internet speed/bandwidth limiting |

Hi FindingFive devs - an idea for a future feature may be to introduce an internet speed check/limit, such that participants with a download (or upload) speed lower than a certain value cannot take part in a specific study. This would be a value that researchers could set, and the bandwidth of a participant would be checked before they begin the study, and could screen them out. I don't know if this is hard to implement, but for myself I know I would find it useful. Just a potential idea.
Thanks for all the great work!

| Multiple sessions open |

It seems that it is not possible to have multiple sessions open at the same time. If that is possible, how do we do it? If it is not possible, I would like to recommend that it be changed so that it is possible. Many people are interested in my experiment and want to check it out for learning or seeing how it works. So, I would like to leave a public facing session open for those people and then run my controlled experiment in another session. It would be nice to be able to do that.

| stimuli of pictures with a random prob sequence |

Hi, I am working on designing an online experiment. There are three stimuli and the probability of winning the reward from the stimuli is fixed. But for each trial, the probability of which ice hold corresponds to which fixed probability will be randomly assigned. So is there a way when designing the experiment, I could randomly generate sequences for different prob and assign them to different stimuli? For example: for the first trial, 30% for left stimuli, 50% for the middle one, 80% for the right one. Then the next trial, 30% for middle, etc) I check the documentation but did not find a parameter that could solve the question mentioned above. I was wondering id there any way I could achieve that? Thank you!

Hi,
Would it be possible to hide the progress bar for the participants? I found it quite misleading. The progress bar seems like there is still a long way to go but actually it's one more click to finish the experiment. Thank you!
Best,
Zoe

| setting up pre-requisites & exporting audio stimuli |

1) I'm on a study of which I'm the collaborator but not the creator. When I try to make a copy of the study, I can duplicate the definitions of the stimuli and responses but not the actual audio and video stimuli. Is there a way that I can export all the audio stimuli from the original experiment/transfer the audio stimuli from the original to the new experiment?
2) When I set up a new session for an experiment, there's a part where I can set up the "Pre-requisites and anti-prerequisites". It says "Use the control key to select more than one study. This is selecting prerequisite studies." However, it seems that I was not able to select any studies even when I press the control key. Could you please provide me with some guidance?
