Polycom RealPresence Trio 8800 Signs out

I have the exact same issue but I am not using Event Zero.  Just a very basic configuration, with a Skype room account.  I have also removed the sign out button, and I have added a custom back ground, otherwise pretty vanilla.  I also asked Polycom with no further information, they only mentioned factory reseting it, which I did.  I must say though after a factory reset, and reapllying the lastest firmware it behaved for a longer time, even a couple weeks I believe.  But now its back to its old ways.  As stated a reboot or restart fixes it.  Interestingly when you lookin in the web UI the skype account is signed in, the account shows offline though, very bizzare.  I am thinking of rebooting it every night as a temp fix as its extremely fustrating to my users.
