I have noticed this exact same thing happening. There is a way to get them turned around so the latest post is first, but it needs to be done each time you go to a topic. At the top, just above the message list, there is a little triangular arrow next to "latest post" that points up or down. If the messages are oldest messages first, click on that little arrow, which I think will pointing up, and it will flip all of the messages so the latest message is first after the sticky topics. I've tried it in several different topics and it seems to work. I just wish it would stay the way I put it!
