Have any of you had a problem with your Acura MDX creeping forward with the transmission in neutral?

You stop at a light put the car in neutral and it creeps forward like it is still in gear...have you had this happen...or have you seen it discussed in a forum or blog?|||I was thinking that too. Maybe you were on a small hill. When you're on neutral, gravity will pull your car in the downhill direction.|||maybe you were on an incline
