Greetings all, I am using the Inquisit OSPAN task in a lab study and it generally works fine, but on occasion we have a case where the task does not run normally.  Specifically:

1) there is no field for the participant to indicate the answers.
2) And it automatically proceeds to the next question too quickly (not the actual time allocated)

Here is a clip of that glitch:

It is very odd because it happens rarely, and it's not consistent.  If we run another participant on the same task an hour later on the same computer, there is no problem.  I have also seen this happen on completely different computer models in different labs. 

Any idea why this might happen?  Thanks for any help!
