    Hey all,

    I seem to have a problem using wxWizard in an XRC definition.

    I've attached a small code snippet which causes a crash when you click 
    Next. If someone could point me in the right direction, maybe to some 
    examples of wxWizard and XRC, that would be great.

You need to use `RunWizard` for wizards, not `Show` or `ShowModal`.  Also you need to explicitly import wx.wizard so the OOR system will know about the classes and so `resource.LoadObject` will return an object of wxWizard type instead of wxDialog.

Here is a working copy of your example:

{{{
#!python
import wx, wx.xrc
import wx.wizard

print wx.VERSION


definition = r'''<?xml version="1.0" ?>
<resource>
    <object class="wxWizard" name="Wizard">
        <title>Test</title>

        <object class="wxWizardPageSimple" name="Page1">
            <object class="wxStaticText" name="label1">
                <label>This is a static text label for Page 1.</label>
                <pos>10,10</pos>
            </object>
        </object>

        <object class="wxWizardPageSimple" name="Page2">
            <object class="wxStaticText" name="label1">
                <label>Page 2</label>
                <pos>10,10</pos>
            </object>
        </object>
    </object>
</resource>
'''

app = wx.App(0)

# Load the XRC resource
resource = wx.xrc.EmptyXmlResource()
resource.LoadFromString(definition)

wizard = resource.LoadObject(None, 'Wizard', 'wxWizard')
page1 = wx.xrc.XRCCTRL(wizard, 'Page1')
wizard.RunWizard(page1)
wizard.Destroy()

app.MainLoop()
