We can't recreate this. I notice that the command does not execute.
Does this happen only once or does it continue to recognise commands?
What is your mic setup?
Can you post a full log?
If it only happens once (and the command is not executed) and then behaves as if it is off, then VoxCommando is behaving as intended. Sometimes the ms sr engine will refuse to turn off when asked. VoxCommando is attempting to deal with this scenario gracefully.
