Subscriber and Citrix disconnected sessions

WE are running Xenapp 5 using Powerfuse 2010 and subscriber file version 2007.8 to lock the workstations. WE do this by running a logon script for an account that enters a registry setting invoking subscriber.

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /t REG_SZ /v shell /d "c:\program files\res subscriber\subscriber.exe" /f

This behavior sets up the computer to pass directly to a published application that is a desktop. The user works in this desktop with Powerfuse as their environment.

We disable the locked behavior with another account that removes the setting and returns it to a normal Windows XP machine. The issue I have is that we can't reconnect to disconnected Citrix sessions and in Citrix the published desktop doesn't show as the application similar to this http://support.citrix.com/article/CTX112922

How can I get this to work so we can reconnect to disconnected sessions
