Any danger in disabling Session Manager in the .mfgsys file?

There is a setting in the .MfgSys file that allows the Session Manger to be disabled. Any reason this would be a bad idea?

I ask, because occasionally users get disconnected, and their remote session gets hung up because SessionManager.exe is still running.

We’re on V8.03.409C, and all users use it via a published Web App (Microsoft’s version of Citrix, I think).
