"Fixed unexpectedly quit issues which usually occurred whilst playing videos, synchronizing photos to the device and also while changing the artwork size in Grid view.
- Proper addressing of iTunes interface elements that were incorrectly described by Voice-over and WindoEyes, thereby creating an issue.
- Fixed unresponsive error with iTunes player while syncing iPod nano or iPod shuffle.
- Resolved ordering problem that occurred while browsing TV episodes in the iTunes Library on the Apple TV."
Ans I thot that Apple never stutters, always "works".
