Okay, I have an inspector and object editor open for the button, but they show no scripts

- How to find out what a button does?

Okay, figured that one out. The cylinder button has:
    this.addScript(function onMouseUp(evt) {
            lively.morphic.Menu.openAt(evt.getPosition(), 'Number of cylinders',   this.menuItems); }).tag([]);
Maybe the editor showing no scripts was on the button label…

LivelyEngine was deleting and rebuilding all the buttons on every click to update the button labels (e.g. in setRunning)
