Microsoft IE patch incompatible with Client Manager UI

All CWA Users,

We have recently found out that Microsoft's recent patch (update KB4012204 - Cumulative Security update for IE 11) which was released this week is not compatible with Cisco Workload Automation. If using a IE browser with this patch, many screens will not be usable in the Client Manager's user interface. Our development team is reviewing the issue to determine the root cause at this time.

Workarounds at this time:

1. Uninstall the patch if you must use IE for Client Manager user interface

2. Use a supported Firefox browser for Client Manager user interface
