IEHtmlWindow and Https issues on Windows Vista

Hi all,

I'm using wx.lib.iewin.IEHtmlWindow and it works great except on
Windows Vista when packaged into an executable via PyInstaller (not
sure about Py2exe).

For some reason, on Windows Vista it will only show http based
requests, and sites that have https (mixed-mode) will not show (the
navigation will be cancelled).

I've tried applying:

to fix it, with no success.

Does anyone have an clue as to how to enable https traffic? It seems
to run fine if I use python, but not so if its bundled. This only
affects Windows Vista (IE/8 it seems).

Any help/comments/suggestions welcome.

Thanks,
