Re: [wxPython-users] wxPython 4.0.0b2 release

Hi Robin,

Thanks so much!  This is working well for me with Anaconda Python 3.6 and
2.7 on OSX (the only system I've tested so far), except that the new wxdocs
and wxdemo (which look very, very handy) don't work for me.  First, I got

    ~>~/anaconda3/bin/pythonw ~/anaconda3/bin/wxdemo
    Traceback (most recent call last):
      File "/Users/Newville/anaconda3/bin/wxdemo", line 7, in <module>
        from wx.tools.wxget_docs_demo import demo_main
      File
"/Users/Newville/anaconda3/lib/python3.6/site-packages/wx/tools/wxget_docs_demo.py",
line 47, in <module>
        import wxget
    ModuleNotFoundError: No module named 'wxget'

I think that was probably meant to be `from . import wxget`.   Making that
change I then get

    ~>~/anaconda3/bin/pythonw ~/anaconda3/bin/wxdemo
    sys.version_info(major=3, minor=6, micro=2, releaselevel='final',

    Launch Demo for wxPython V4.0.0b2
    Looking for wxPython-demo-4.0.0b2 at
/Users/Newville/Library/Application Support/wxPython
    Looking for cached /Users/Newville/Library/Application
Support/wxPython/wxDocsDemoCache/4.0.0b2/wxPython-demo-4.0.0b2.tar.gz

and the Dialog with "Download Prompt" pops up asking if I want to download
the demo tarball.  Hitting 'Yes' results in the traceback below, ending with

      File "/Users/Newville/anaconda3/lib/python3.6/ssl.py", line 688, in
do_handshake
        match_hostname(self.getpeercert(), self.server_hostname)
      File "/Users/Newville/anaconda3/lib/python3.6/ssl.py", line 321, in
match_hostname
        % (hostname, ', '.join(map(repr, dnsnames))))
    ssl.CertificateError: hostname 'extras.wxpython.org' doesn't match
either of 'alldunn.com', 'www.alldunn.com'

When I go to that site in a regular browser I see "connection not secure"
messages, as if https is not certified.  If I accept the risk and proceed
anyway, it doesn't seem like the place I was looking for...

Hope that helps, and thanks very much!
