为什么Windows中的wxPython中的MenuBar项延迟，而osx中的instant呢？

Question

请参考下面的精简示例脚本。当我在OSX中运行这个时，菜单栏的行为和您期望的完全一样。然而，在Windows中，“Slow”菜单项的呈现有一个明显的延迟（我的2GHz Core 2 Duo大约有4秒）。这感觉一点都不正确，让一个应用程序显示好的旧的(Not Responding)警告并不是您在菜单中单击后所期望的行为。在

以前有人遇到过这个问题吗？我是不是在Windows端做错了什么？在

至于版本，我用最新的稳定版本2.8.12.1和开发2.9.2.1进行了测试，我运行的是python2.7。在

后来我把这个贴在wxPython列表上，得到了this的回复。真的没什么错，只是XP就是XP而已。在
