Currently, running Netflix on your Android 4.3 device causes the device's power lock button to become unresponsive once it's put to sleep. Definitely an annoying bug and you can be sure Google and Netflix are currently working on a fix ASAP. According to Google's own Dan Morrill, “top men” are currently working on a fix that will be pushed as soon as it's finished.

Until then, the only way to revive the device is to hold the power button until it restarts. We'll let you all know once the update is pushed!

Google, since you, or Android, or Asus or whoever sent the 4.3 update, my Magic Jack apps will not load. MJ is working on it, Google Support says speak to the OS writer.
Pass the buck all you want, just write a fix for the Magic Jack App PLEASE it will not work since the Upgrade to 4.3 on my Nexus 7 tablet.
