We've had other odd little things, too, like users getting a 'page cannot be displayed' error page after posting, and yet when they go back and look, the post actually went through just fine. And a lot of users are reporting that the picture that posts ends up being the default, no matter what they select. That's not quite as disturbing to the users as the friends list issue though.
Anyone have an idea or suggestion? We're a little hesitant to try another upgrade so soon using CVS, especially as we're not sure if there's an underlying problem we should correct first.
Thanks for any guidance or tips anyone can provide.
