To provide some closure for the original question, it looks like SpinCtrl on OSX requires the use of a Wx sizer for proper display.  Without the sizer, weird things can happen.

Quote - self.divparm = wx.SpinCtrl(self, value="10",pos=(145,0), size=(50,20))

No sizer, bad.

Quote - sctrl = wx.SpinCtrl(self, value="64", min=35, max=75, initial = 64)
        sctrl.SetMinSize((150, -1))
        sizer.Add(sctrl)

Sizer, good.
