    Hi Sebastien

    I am experiencing an issue that the newest version (2.9.2) did not fix.

    I have created an experiment that runs in two playback modes (green play button, and orange play button), but which randomly ends early in the full screen mode (large green play button). It has worked intermittently, for no apparent reason. But the majority of the time, it will not. Not sure if this matters, but I am using the Experiment backend. The experiment is a Posner Dot Task.

    Hi Yvette,

    Could you provide some more information? E.g., what happens exactly when the experiment ends early. Is there an error message in the debug window and/ or an opensesame.exe.log file (on Windows)? And if so, what's the error message? Details, please!
