Just a quick update to this situation...
We have fixed the sign-off/comment bug discovered by HIFM (THANKS!!) and we have indeed discovered that there is a Synch utility bug as well. Both have been fixed, and we are now in the process of internally testing these fixes and the new installation package to ensure we've actually fixed the problems without introducing other issues.
We expect our internal testing to be completed by tomorrow afternoon and providing we don't find an issue, we expect to release the new build (V4.0.73) tomorrow evening.
