Thanks for the example, it helped me verify that what I had was correct.
I cut out all of a date picker's parameters and pasted it back to how it was - it automagically worked after that with the same XAML. I fixed the rest of my date/time pickers this way. I still think there's something weird going on.
Possibly related: Every time I click on a date picker in VS Designer (2010RC), the calender opens up and does not go away even if I click on something else to change focus.
