Py2app防止wxpython打开第二个wx.Frame

Question

我有一个python脚本进程的Quicktime文件，而这个过程可能需要相当长的时间来执行和完成，我有第二个窗口打开(它打开并停留在其他一切说'请等待'，BusyWindow类)，然后关闭完成时。在python脚本形式下，这一切都可以正常工作，但是在创建Py2app(它将包括wxpython在内的所有内容捆绑在一起)时，第二个窗口无法打开。虽然仍然打开，如果我再次运行它，第二个窗口现在打开。我看过另一个关于这个问题的帖子，但没有修复，有人有任何建议吗?

今天晚上我为这个问题纠结了好一会儿。将py2app中的argv_emulation选项设置为False似乎有效。

启用时，argv_emulation捕获某些AppleEvents，这些事件被转换成字符串并填充到sys.argv中。当与使用GUI工具包的应用程序一起使用时，我怀疑这会吞噬wxPython期望接收的一些AppleEvents。
