As a user, I’d be upset if anything more than a notification came up. I might be in the middle of something and willing to ignore calls from some people. I think this type of situation (switching in without user interaction) should be covered in the iPhone HIG. If it isn’t, a bug should be filed. Guidance here would be useful to maintain user sanity and application continuity. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
