So an 4.0.3 upgrade to the OS was pushed. Before the upgrade I just tapped the power button and the device would go to sleep. Then another tap woke it up, ready to go. Now, after the upgrade, when I tap the power button I get a dialog asking if I want to power down. If I reply "no", the tablet goes to sleep. For a short while. Then it starts to flash it's screen at me: Turn on, go dim, go off. Rinse and repeat. I guess the tablet want's to be off between uses? But that forces me to sit through a restart when I turn it back on. Anyone else seeing this?
