Suddenly someone's username on my team has changed, he did not change it. Security Issue?

[Adam Czyrek]

I have had a chat room open for many months.  Suddenly overnight one of my co-workers username, as displayed in the chat, has been shortened, and he says he did nothing to change it.

Previously his name was something like: John Kline Franklin

Suddenly it shows as: JohnF

Apparently my username still has normal 2 word formatting.

For more detail, the chat thread still has John Kline Franklin in messages in the thread which were posted prior to today.  Then any message from today says JohnF.

What's going on here?
