Hi Mark,

Please see my answers below:

There's some magic in the Tk-Cocoa help menu--if you define the 
tk::mac::showHelp command and map it to your function that calls user 
help, you don't need to add a separate entry for help. (There's already 
an entry hard-coded for help, along with the search field.) So the 
helpMenu.add_Command(label="Help")... stuff is redundant.

If you're just running the app from Python and not wrapping it with a 
tool such as py2app, this is the expected behavior.  The "about" menu 
picks up the name of the executable from its info.plist file, which in 
this case is Python.

>      Help
> 	Search # some apple-specific thing that just appears
> 	ActivePython3.2 Help # invokes my help action
> 	Help                 # invokes my help action

See above--you need to wrap this as a standalone app using py2app or

If you don't add any items to the help menu but just define it, I would 
expect to see an entry called "ActivePython 3.2 Help" that calls up a 
dialog which says, "Help isn't available for ActivePython 3.2."

This is how I set up my help menu is one of my Python apps:

	        self.createcommand('::tk::mac::ShowHelp', self.runHelp)

        self.helpmenu = Menu(self.mb, name='_help')
         self.mb.add_cascade(label='Help', menu=self.helpmenu)
         self.helpmenu.add_command(label='Phynchronicity Help', 
         self.helpmenu.add_command(label='Contact Code by Kevin', 
         self.helpmenu.add_command(label='Web Site', 
         self.helpmenu.add_command(label='User Forum', 

Hope this helps,
