BTW, it's usually better to report each problem in a separate email. 
Then it's easier for people to answer one or the other if they don't 
know both.

This is a known problem, but Stefan hasn't yet found a solution.

Since there are some differences between various platform standards on 
Mac and the other platforms, wxMac tries to help you conform to the 
Apple HIG without needing to put a lot of conditional code in your app. 
  One of the ways it does this is to move standard menu items to the 
appropriate place, as long as you use the standard IDs.  As you 
discovered a menu item with an ID of wx.ID_ABOUT gets moved to the app 
menu, so does an item with an ID of wx.ID_EXIT and wx.ID_PREFERENCES. 
If you don't want to use standard IDs for these menu items then you can 
tell wxMac which items are the special ones using some static methods of 
wx.App, here are the C++ signatures:

     static void SetMacAboutMenuItemId(long val);
     static void SetMacPreferencesMenuItemId(long val);
     static void SetMacExitMenuItemId(long val);

BTW, there has been some work in 2.9 on how the Help menu is dealt with, 
so I don't think you'll see the same issues with it anymore.
