James,
I am your #1 fan!!
I noticed recently all the improvements you have made under the hood in the ObserverRegistry...
I have a request for you. Will you include a vi in the queue messenger library that is simply queue status? I've made this vi a time or two, to see if a actor gets behind, the problem is that when I switch to a different computer, or update the Messenger library from the repository, this QueueStatus vi is lost......
