Over the weekend, several of my applications were updated. Now, I'm getting random "Synchronization started" popups on the lower portion of my screen. It's only there for a second or two, then it goes away. I've had it show up over the home screen, and over several of the applications. Does anybody know where these messages are coming from, and if they can be disabled? Am I the only one seeing them? I don't recall seeing this message appear before the weekend.
