That doesn't explain why a cover in a Normal Glo works perfectly, and when you take the normal Glo out and place the Glo HD in it not.
I had 2 normal Glo readers and my Greek one, all 3 works perfectly with the normal Glo but they don't with the Glo HD, so either the magnetic switch inside is moved slightly, or the screen is thicker so the magnets in the cover must be stronger.
