I recently added the Quartz framework and a PDF_View to my app. The PDF_View works great except for these warnings when I start my app: 2010-08-12 10:49:45.297 MacDriverLog[265:a0f] [QL] image sp_zoomp_handle not found 2010-08-12 10:49:45.300 MacDriverLog[265:a0f] [QL] image sp_zoomp_track_left not found 2010-08-12 10:49:45.301 MacDriverLog[265:a0f] [QL] image sp_zoomp_track_center not found 2010-08-12 10:49:45.304 MacDriverLog[265:a0f] [QL] image sp_zoomp_track_right not found 2010-08-12 10:49:46.331 MacDriverLog[265:a0f] __CFServiceControllerBeginPBSLoadForLocalizations timed out while talking to pbs Do I need to be concerned with these messages? Although my PDF_View works both for display and printing, My other views now create an invalid graphics context when printing although they still display OK. After the call to beginDocument, NSPrintOperation.currentOperation.context is nil and NSGraphicsContext.currentContext.graphicsPort is invalid. Calling NSPrintOperation.currentOperation.createContext changes the context to NSPrintSpoolingGraphicsContext but then my app just hangs. Has anyone experienced this problem? I am using MacRuby 0.6 stable release. Thanks for your help, Bob Rice
