Description

This article is intended for Citrix administrators and technical teams only.

Non-admin users must contact their company's Help Desk/IT support team and can refer to CTX297149 for more information.

Users connecting to a published desktop and from inside the published desktop they launch applications from Citrix Receiver. Once launched, they disconnect from their session and try to reconnect to the same session.

Users will reconnect to disconnected sessions, but the open applications go to the background instead of staying in the foreground randomly. These applications are enumerated and launched from XenApp 6.5 as well as XenDesktop 7.8 farm.
