How to set each photo in to auto exposure in LR3 develop module?

This shouldn't be this hard, but I can't figure it out.

I'm brand new to LR3 so bear with me. For snapshots I find that the "auto" button in the exposure section of the develop module works just fine and is much faster than I am.

In ACR in CS2 I could select multiple photos and select "auto" and voila.

In LR3 I select them all and click on auto and only the single picture showing gets adjusted. It doesn't appear in the sync window.

Ideas?
