I am one of the two page turn anomaly folks. I am also one of the people who beta test the Touch.
So far, there are just two of us with this problem that I know of. I have sent my sqlite Db to Kobo. They played with it and determined that it was not part of the problem. I am working with Kobo staff to figure it out. Our plan for the weekend includes me making some videos of the problem as it exists today, another after a factory reset and installation of the last beta before the release version, and then with a new release version applied. If the problem persists, then I will box up my Kobo and send it to the development teams for them to take a deep look whilst they send me a new device.
Even when a problem appears to only affect a very small number of users, the developers work very hard to understand and correct the problem. Amazing folks!
