Did you install the Database and Server Behaviors extension first? Order may matter.
I could set up a screen sharing session to look into this with you and get it resolved. You are the first to report it and I haven't seen it on my end. It is possible that it is an issue with the page itself. If you send me a copy of the site definition and the page you are working on I could try to reproduce it on my end and if I did I'd be able to fix it.
