Jon and Bryan, thanks for the replies. As far as the Firefox popup issue, it is not a big deal - I just did not know if anyone was aware of it or not. On the Upcoming Events being empty at login, I think I will install 1.3 on my real site and see if the behavior occurs. Since no one else has complained and it can't be reproduced, it is probably something particular to my test site. I will post again if it happens on my production site (it is on a completely different web host).
Many thanks for all of your work to make Moodle even better than it already is!
