Error message when running experiment on Superlab 6.0

Everytime I open my experiment on Superlab 6.0 - which was running normally on Superlab 5.0 - I receive the following message: “Your setting prevented event XX from ending. You specified that a response must fall inside on-screen stimulus boundaries, but no stimulus is visible during this experiment.”. Do you have any idea of what that means?

Thank you for sending us the experiment. We were able to duplicate this bug and a fix will be included in an upcoming SuperLab 6 release.

We’ve released SuperLab 6.0.2 which will fix the bug that you reported.
