I just started running tutorial on wxPython (2.8.11) and noticed that by using standard IDs menu bar is not working. I have Mac OS X 10.6 (64-bit, latest updates), Python came with Mac, no updates where made (2.6.1). Python runs on 32-bits by setting VERSIONER_PYTHON_PREFER_32_BIT=yes environment variable.
This code example was tested: http://wiki.wxpython.org/Getting%20Started#Adding_a_menu_bar
After launching application we can see "File" menu, but after pressing we don't get full menu, there is no "About" and "Exit" items. But if we change wx.ID_ABOUT and wx.ID_EXIT to random other numbers menu does work as expected. Looks like there is some problems with Mac OS X and standard IDs?
By using example (File menu does not show up):
By changing standard IDs to random numbers 10 and 20 (File menu does show up):
