Question on Private messaging

[David Noble]

I just checked and I’m still getting the message tree. I didn’t see any way to change it back and forth. If John gives an answer I’d be interested in hearing it.

One possible explanation, is when the sender is replying to you, he may delete the previous message, and, while still replying, is only sending new info. I do this some time, because they get so long, and sometimes aren't parsed in order.
