EVT_LISTBOX broken on OSX?

[7stud]

Hi,

On an imac with os 10.4.7, the EVT_LISTBOX event doesn't fire if I click on 
an item that is already selected:


import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, "List Boxes")
        panel = wx.Panel(self, -1)

        choices1 = ["red", "green", "blue"] 

        self.listbox = wx.ListBox(panel, -1, (10, 10), (100, 200), 
                                               choices1, wx.LB_SINGLE)
        self.listbox.Bind(wx.EVT_LISTBOX, self.on_select)

    def on_select(self, event): 
        selection = self.listbox.GetSelection()
        print selection

app = wx.PySimpleApp(redirect=False)

win = MyFrame()
win.Show()

app.MainLoop()
