Hi,
Not sure if this is the right place, but the nightly builds going back a fair while have the same bug where when you join a conference room the user list is blank, the space is there, but nothing appears.
The rooms appear to work fine otherwise, but not having a member list is frustrating.
2.6.3 stable release is fine.
I also tried changing themes and deleting my profile under appdata with no change.
Im after XEP-0184 support in the Smack API which was just rolled into a nightly build!
Thanks
Christian
