MacBook doesn't sleep when closing lid with external monitor attached with Lion

Up until yesterday (with Snow Leopard), closing the lid would cause my MacBook to sleep whether or not the external monitor was connected.

Since upgrading to Lion last night, closing the lid when the external monitor is attached just tosses all windows to that screen and keeps going.

I realize I can sleep via the Apple menu or keyboard before closing the lid. I'd rather not have to, and I'm wondering if there's a setting to restore the sleep-on-close behavior.

Mac OS X (10.7)

My Macbook pro wouldn't go to sleep. So I started playing with some of the sharing settings. File Sharing had no effect, but when I turned off Internet Sharing it was snooz time. 🙂
