The same issue describe above was just reported to me too, using the following; Software release: Loway QueueMetrics - 15.02.2
B: 5353 2015-03-13 09:24
Note: using the new agent page, when select pause code the wheel just keep spinning and after a while it stops however the agent is not paused. the only way it works is to totally log out of the queue then log in again then use the pause function and then it works.
