Hi Rosa,
I was testing your code with a new version of PennController that I hope to release soon, in which I fixed a bug with the Key element, that’s why I didn’t encounter the problem you described. However, as of the latest official release (1.8) that bug still hasn’t been fixed, so you’ll need to replace .log("first") with .log("all") and the problem should go away
Let me know if you still experience problems
Jeremy
