This bug is only in the latest release build 3.1.7-pl1, it's not in previous build 3.1.6.
Bug: Logged in user not showing in a logged-in users list after a time period without refreshing the page twice.
How I discovered this:
1. User logs in and active session is limited to ie. 1 minute
2. Refresh page to start timer.
3. Refresh page again after 1 minute is gone.
4. User is not showing in a logged-in users list. <-BUG
5. Refresh page again, user is showing in a list.
It's a small but annoying bug Please fix!
