Sorry, but it doesn't happen on Sonys. I can't speak for other brands. Or, perhaps I should say; it doesn't happen on the two Sony's we have, or the ones I looked at in the shops. The only time you can see this happen is when the reader has been turned completely off, then turned on again. It doesn't occur between page turns. That is NOT something I would care to see on a regular basis.
