Hi Gray,
The devices aren't staying registered with systemadmin, teachertest OR standard user types, promethean thought it may be something to do with the tick in the read only box of the documents and settings filtering down to the device registration folder, but that tick reappears when the user logs off and logs on again, it is a standard setting with the RM CC3 network I think.
We do have the system working on a standalone laptop!
Thnks,
Laura
