It's really the weirdest thing. No matter how I try, i cannot replicate the sleep/wake issue when bending the cover back. My iPad goes to sleep when the cover is in the closed position. Once I open it, no matter how much I push down on it when it is folded completely back, it will remain "awake".
I am wondering if there are different builds of this case, whether one or the other would display this problem. (say for instance if the magnetic field in one, was stronger than the other.)My present case is the red one, I will be receiving the brown sometime in the next week. It'll be interesting to see if this issue manifests itself then.
