This problem seems to be an issue in 2.10. I had not noticed it in the previous versions, so I think it's something new, perhaps introduced by the improved battery management. What appears to happen is that you flip the flip bar normally, but the operating system appears to hang for a short while. This is apparently treated as a long flip, which results in the 5-page skip we're experiencing.
Just guessing. And I still love my iLiad
