    When I try and run the questionnaire sample experiment, I get the following error after the first answer:

    Error: Runtime error
    Description: usanitize() expects first argument to be unicode, not ""

    Hi Jákub,

    Thank you. Indeed, the multiple_choice plug-in is broken in OpenSesame 0.27. However, please see my post here for an alternative.

    Hello Sebastiaan.
    Thank you very much for your prompt reply. Will the plugin be fixed in the final version of 0.27, or are you moving away from this plugin?

    Best regards,

    Both, actually. Since this is only a minor bug, I'll fix it for those who still want to use the questionnaire plug-ins. But minor updates aside, the forms are intended to fully replace the questionnaire plug-ins.

    There seems to be some bug in the form_text_input item. When using it, even when simply using the default template, the following error message is displayed, when you try and edit the logger's script and press "Apply and close":

    "unbound method var_info() must be called with form_base instance as first argument (got qtform_text_input instance instead) (Edit the script to fix this)"

    I'm using the pre-32 build.

    Best regards,

    Ah, thanks for pointing that out. I encountered a similar bug a while back. It should be fixed as of 0.27~pre34. But the issue it's kind of difficult to reproduce, so let me know if it still occurs.

    I love it when you put up a new pre-release package! I get so excited and can't wait to get home and try it out :)

    Best regards.
