This happens to me a lot. I will post an answer to a question, and the system awards me 50 points. Then it refreshes the page and the points (as shown in Today's Points) is taken away. Sometimes if I post an answer later in the thread, it will give me the 50 points and not take it away after the refresh. It doesn't do that when I post a question, but we will see about that this time.
OK - on another thread, I posted a question and did not get points.
