This is the second ever report of this behaviour we've received, and we haven't been able to reproduce it here.
By design whether the failure steps pass or fail has nothing to do with whether a success or failure is returned to the parent script. I assume there is an obscure bug that causes this to happen in rare circumstances.
If you can provide a reproduceable example of this behaviour (to
support@kinook.com) either by tweaking the sample we provided in the related thread (
http://www.kinook.com/Forum/showthre...=&threadid=448) or your own project, we should be able to resolve the issue post haste. Otherwise we must first recreate the problem (a needle in a haystack search we've already expended resources trying) and then fix it.
