Problem with wxPython listbox

[DisAstro]

Hey all. I'm trying to write a simple application, to calculate the odds for poker. However, I have run into a problem.

The idea is that the user selects both cards he/she has, use a checkbox to set if they are suited or not, and finally, press Calculate.

The strange thing however is that I can't select anything in either of the boxes!! The checkmark works fine, but the boxes just won't work correctly. Can anyone help me out?

"Pure Box Script"

        self.box1 = wx.ListBox(self, -1, size=(60,163) , choices=['Ace','King','Queen','Ten','9','8','7','6','5','4','3','2'])
        self.box2 = wx.ListBox(self, -1, size=(60,163) , choices=['Ace','King','Queen','Ten','9','8','7','6','5','4','3','2'])
...
        self.sizer.Add( self.box1   , ( 1 , 0 ) )
        self.sizer.Add( self.box2   , ( 1 , 1 ) )

Some changes since yesterday:
Added ID's and binded them to a simple print selection function. No change at all. Anyone?
