This is rather the nature of undefined behavior though – when in the task switcher we try to update your image, but may suspend the application at some point. But since you aren’t necessarily in the background, we may not *kill* the application. The application being unable to respond in time for a snapshot is what may result in the snapshot behaving oddly, and a suspended application may not respond in a timely fashion. > This is really weird behaviour.

That doesn't really make sense > to me… Honestly, just remove UIApplicationExistsOnSuspend. Its simply not a behavior that is expected of modern iOS applications. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
