Can anything be done about the slow load times for wx.Choice widgets?

Some widgets just take forever to load on Windows. In my particular case, it's wx.Choice

Robin Dunn himself has blamed this on Windows and not wxWidgets (https://groups.google.com/forum/#!topic/wxpython-users/gODkIvyj-nU)

I don't buy it. I can create a similar UI in tkinter and it will be nice and fast on Windows.

I will create demo programs of the same interface in both and then take those to Robin on stackoverflow. Other than asking the creator, I don't have any ideas for fixing this.

This remains outstanding, however the GUI is none-the-less working well enough to use. Moving this out.
