Hello Kris,

I think the specialists are in the wxPython-mailing list ;)
http://www.wxpython.org/maillist.php

You mean a wx.TreeCtrl?
I don't understand exactly what you mean with "properties".
Do you have a sample program?
Sorry for not helping much.

Is the properties window a wx.Dialog?
If you show it with ShowModal(), then you must 
finish with it, before you can select another tree node.

There is a wxPython book in process, and it is publication is estimated
around end of this year.
