My guess (but since there is no info, it's just a guess) is that you are using the v1.19.2 branch of the Cool VL Viewer and trying to interact with a scripted object which needs for newer viewers' face detection on touch. Such a feature does not exist in pre v1.22 viewers, so if you want to play with that object you will need to use the Cool VL Viewer v1.23.5.
Note that you can have both branches installed on your computer (simply isntall each branch in a different directory) and switch between them when needed.
