I don't even know how the wx.TR_HIDE_ROOT is supposed to make the tree 
to behave.

It 'works' for me and doesn't crash. Are you using new enough versions 
of Python, wxPython and PythonCard? My environment is:

    PythonCard version: 0.8.2
    wxPython version: 2.6.1.0
    Python version: 2.4.4 (#71, Oct 18 2006, 08:34:43) [MSC v.1310 32 
bit (Intel)]
    Platform: win32

The only thing I can make wx.TR_HIDE_ROOT to do is hide the whole tree 
and I can never get it back to visible again. I do this on initialize:

        tree.SetWindowStyleFlag(wx.TR_MULTIPLE) # <== added by JS
        self.initialFlags = tree.GetWindowStyleFlag()
        tree.SetWindowStyleFlag(self.initialFlags | wx.TR_HIDE_ROOT) # 
<== added by JS
        print self.initialFlags

and it hides the tree alright but then I have a button with code that is 
supposed to do the opposite i.e. make the tree visible again but doesn't:

        tree = self.components.tree
        print tree.GetWindowStyleFlag()
        if tree.GetWindowStyleFlag() & wx.TR_HIDE_ROOT:
            tree.SetWindowStyleFlag(self.initialFlags)
        else:
            tree.SetWindowStyleFlag(self.initialFlags | wx.TR_HIDE_ROOT)
        print tree.GetWindowStyleFlag()
        tree.redraw()

I tried tree.Refresh() also with no avail. But on the bright side is 
that it doesn't crash ;)

Sorry I can't be of more help

Cheers,
Jussi
