hmm -- I'm pretty sure that PYSipleApp is deprecated because it
doesn't actually do anything -- though it way chance a default or two.
One to look at is crating the app:

app = wx.App(True) will create an extra wx.Frame to capture stout.

app = wx.App(False) will not, and will not re-direct stdout.

yup -- and wx follows the Windows/GTK conventions here, so you have to
kludge a bit to get proper Mac behavior

I'm still a bit confused -- if you build an app the regular wx way,
and it works right on Windows and Linux, then you should get an app
that goes away when you want it to stay alive, not the other way
around -- so I would expect you to need to figure out how to keep it
alive. IIUC, the way to do that is to create a dummy wx.Frame -- it
will keep the app alive, and give you a menu bar. See this SO thread:

where are you binding that? to the Frame? It's usually a wx.frame event.

Take a look at this:

http://wiki.wxpython.org/Optimizing%20for%20Mac%20OS%20X

Which does not address the question at hand, but may address other
questions...And if/when  you find a solution it would be great if  you
would add it to that page!
