title: I've added style=wx.te_Multiline to my wx.textctrl item but my scroll bar is not working
body: <p>I would like for my TextCtrl field to gain a vertical scroll as I write events out on it.</p>
  
  <p>The code I have so far is;</p>
  
  <pre><code>sizer = wx.BoxSizer(wx.VERTICAL) #Create a vertical sizer
  
  #Create our multiline console area          
  self.term = wx.TextCtrl(self, -1, '',  style=wx.TE_MULTILINE) 
  
  #Add our console to the sizer
  sizer.Add(self.term, 5, wx.EXPAND | wx.TOP | wx.BOTTOM, 0) 
  
  gs = wx.GridSizer(1, 3, 0, 0) #Define the grid layout in rows, columns
  
  gs.AddMany([
      (wx.Button(self.panel, 3, 'Browse'), 0, wx.EXPAND),
      (wx.Button(self.panel, 1, 'RUN'), 0, wx.EXPAND),
      (wx.Button(self.panel, 2, 'QUIT'), 0, wx.EXPAND) ])
  
  #Add our defined grid layout above to our sizer                 
  sizer.Add(gs, 1, wx.EXPAND)
  
  self.SetSizer(sizer) #Pass &amp; show our sizer
  </code></pre>
  
  <p>I get a scoll bar, it however does not respond to mouse clicks. What am I doing wrong?</p>
