Hello,
I've got the following problem in EP7: when you hit logout, session is preserved for one more minute, in a strange way. From one side I'm logged out from EP and have to provide password to login again [perfectly normal situation], however in Collaboration window I'm marked as still logged in (green icon) and when logging within a minute I got popup that my users is already logged in and all realtime services will be disabled. After one minute everything comes back to normal.
