To give some more detail... Several clients are seeing the same issue. But it doesn't follow the user accounts. Same user, different location, can't reproduce the issue. Different client in location with the issue it can be reproduced. For example: Data Centers and Locations are very distant from each other geographically. Data Center A with VDA A Data Center B with VDA B Location C with workstation C Location D with workstation D C to A issue not reproduceable C to B issue not reproduceable D to A issue happens D to B issue happens We will be gathering additional Locations and Workstations to gather more information. Rumor is that at least one other workstation at location D has exhibited the same symptom. Several workstations at location C have been tested and not been able to reproduce the symptom. It may be something location related like the firewall or network. It may be software installed on the workstations at location D. We are going to continue to gather data and see if we can find something in common with the locations and clients.

Seems that the "use video codec" setting has resolved the issue since Thursday. Thanks again @Steve Noel
