Without actually running the code (so this may not help), have you 
considered binding the events to the panel rather than the frame?

In other words, change

          self.Bind(wx.EVT_LEFT_DOWN, self.OnLeftClick)
          self.Bind(wx.EVT_LEFT_UP, self.OnLeftClick)

          Panel=wx.Panel(self)

to

          Panel=wx.Panel(self)

          Panel.Bind(wx.EVT_LEFT_DOWN, self.OnLeftClick)
          Panel.Bind(wx.EVT_LEFT_UP, self.OnLeftClick)
