dialog icon bug -- mac os 10.4.7

[7stud]

Hi,

wx.ICON_QUESTION 
produces an exclamation icon.

wx.ICON_EXCLAMATION,
wx.ICON_INFORMATION, 
wx.ICON_ERROR
produce a generic python icon.


Example code:

---
import wx

app = wx.PySimpleApp()
dlg = wx.MessageDialog(None, 'Is this cool', "Hello world dialog box", 
        wx.YES_NO | wx.ICON_QUESTION)
result = dlg.ShowModal()
dlg.Destroy()
