Error when renaming items in Jazzy James 3.1.3
So I've been using Open Sesame for a few years now, using it to teach students the basics of programming a psychophysics experiment. However, this year, we are having major issues with the 'Jazzy James' version. Specifically, whenever we attempt to rename objects, we keep getting the same error message (see attached). Interestingly, the name change is present in the tab at the top of the screen but is not in the experiment overview. I'm enclosing a screen capture, and the experiment file. This error is making OpenSesame unusable - so any suggestion as to a fix would be very appreciated.
