If you are not seeing the Calls In Queue window popping when there are calls in queue and you have verified that you are a member of that queue to be an eligible agent, ensure that the time on the PC is correct. If it is off, you will experience delays in this screen populating. This delay will be equal to the time drift of the PC. If the clock is off by 2 minutes, the Calls In Queue window will not populate for 2 minutes.
