Session only 'Disconnecting' on application close

[insanity1]

I have re-installed Citrix onto one of our servers to rectify another issue (it would stop checking in several times a day... this is resolved now)... now on this server there is an issue with sessions going into a 'disconnected' state rather than being closed out all together. I have tried a registry entry that somebody has suggested to use in another post, but it does not appear to correct this problem as it is still occurring...

This is the entry that I added:
to key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI]
entry:
"LogoffCheckSysModules"="ssonsvr.exe"

...there are generally 3 processes that remain running:
the application (such as outlook.exe or winword.exe)
wfshell.exe
and ssonsvr.exe

any thoughts would be appreciated. Thank you.

Are the users actually logging off, or just closing the application with the 'X'? Is this a published app?

Yes, these are published applications within our Citrix environment.

The users either going File > Exit... or closing via the 'x'. It really depends on the user. Their sessions are not terminating when they close the application, processes remain running with the session in a 'disconnected' state.
