xcode - kCGErrorIllegalArgument : _CGSFindSharedWindow?

Question

在尝试编写具有自定义背景的简单 Cocoa/Applescript 时(按照本教程 http://www.mere-mortal-software.com/blog/details.php?d=2007-01-08 )，我在调试器中时不时地收到以下错误:

Error>: kCGErrorIllegalArgument: _CGSFindSharedWindow: WID 3162
Media Center[10234] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

所以我在CGErrorBreakpoint处设置了一个断点，得到了以下结果:

我不完全确定如何解决这个问题，如果需要，我将提供更多输出信息。

编辑:如果您在显示扩展坞时打开应用程序，我会收到错误消息。如果未显示扩展坞，则通常可以正常工作。

我也遇到过类似的问题。您是否尝试过在窗口属性面板中选中“关闭时释放”复选框？
