Hrrrm, I'll let someone who has more experience with LabVIEW try to help you then (the calling scheme is different than for other languages). If you'd try commenting out the autonomous (or finding a sure way to terminate it), that'd probably be a decisive answer to your problem (or, rather, if what I thought is true. It could understandably be something else, in which case we'll have to wait for someone else).
