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)

I have the same problem too: MBP wont sleep unless i manually select it, but i just unplugged my external monitor and now it works like its supposed to.

i check console, and it was complaining said:

kCGErrorIllegalArgument: CGSGetDisplayBounds: Invalid display 0x04272d80

_NXGetScreenRect: error getting display bounds (1001)

this was repeated 4 times, followed by:

EDID does not contain Extended EDID, not valid for audio

which i can only assume is becaus it is pluged in using a DVI adapter (i.e. no audio, therfore not really an error)
