 Skip,
 I had the same thing happen a few days ago.  The door acted the same
 way.  My door popped open when I lowered the flaps turning downwind to
 base.  The air flow deflection caught it just right and POP.  I
 continued my landing at 85 kts.  After landing my inspection noted no
 damage whatsoever.

 I was climbing through about 9,000' at about 145 KIAS in my ES when my
 baggage door open light came on.  I've seen that periodically before and
 all it ever meant was that the microswitch that touches the door needed
 adjusting.  Today though, it was telling the truth because within about
 a minute, it got pretty cold and breezy in the cabin.  I looked over my
 left shoulder out the rear window and sure enough, the door was wide
 open.
