My screensaver has never experienced this problem with any OS version. You *are* using the correct NSUserDefaults object, right? [ScreenSaverDefaults defaultsForModuleWithName:@"your module name"]; instead of NSUserDefaults.standardDefaults. I've mentioned this to you before, but what I'm guessing is happening is that your screensaver is experiencing the same thing that all legacy screensavers are seeing, which is that they no longer get stopped when the user wakes the screen. The process named "legacyScreenSaver (Wallpaper)" loads and runs your screensaver views, but they broke it some time back, and it no longer tells them to stop. This is very easy to see by looking at all processes in Activity Monitor. Start and stop the screensaver multiple times and you're bound to end up with multiple instances running for every screen. I've added code to kill the owning legacyScreenSaver process when my last view receives the @"com.apple.screensaver.didstop" notification, which I added an observer for on screensaver start, keeping a global count of how many instances were started and stopped via the notification. -- Steve Mills Drummer, Mac geek _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
