I Hit on a post today that required a Queue function "work-a-round"
The Poster simply wanted to reset the property "Queue.MaxLen" and that property is quite buried. (and look at the bug in probes on queues where "number of elements in queue" must = "0").
One solution was: 
A better (IMHO) solution would be to drop the "set" method of "Get Queue information" function on the BD and solve the problem with a single call of a vi.lib object.
