Horizon 7.0.2. Windows Server 2012 R2 RDS farm configured for remote applications. Clients and farms configured with PCoIP. Applications virtualized with App Volumes 2.12. UEM 9.01.
With 4.x clients, we sometimes experience issue where View Client goes full-screen with ribbon bar along top when access an app. Seems to occur on first launch of application (ie Chrome or Word). Once application is closed, then opened again, the app is presented in it's own window as desired.
We do not see same issue with 3.5.x View Client.
I've seen this issue on both Windows 7/10 and MacOS clients.
