That means that KVO is going to call the view’s observeChange method on your background thread, not on the main thread. Which I believe qualifies as “updating the UI from a background thread”, which is illegal. It may be that the view has fail-safe code to check for this and ignores the change. Have you checked the console for warnings? (Disclaimer: It’s been way too long since I did any serious AppKit coding, so for all I know, maybe this setup is legal now. But this does seem a likely reason why things aren’t working.) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
