Thanks Igor. I had the same questions as you. However, I downloaded that new version, and tried but I got same results (the behaviour of the first email). I mean, when I did step over in the api call I landed in and in MethodContext(ContextPart)>>runUntilErrorOrReturnFrom:

If that happens then you haven't updated your image. You can verify this by looking for both implementors and senders of #tryInvokeWithArguments: - there should be exactly one implementor (ExternalFunction) and one sender (ContextPart).
