I don't seem to be able to create the editor ( probably because it
is all new to me).

I *can* click in a cell and then scrolling works properly. I tried this
but I don't get the cell editor ;(

class TestFrame(wx.Frame):
     def __init__(self):
         wx.Frame.__init__(self, None, title="Grid Table",
                           size=(640,480))

         grid = wx.grid.Grid(self)

         table = TestTable()
         grid.SetTable(table, True)
         grid.SelectBlock(0,0,0,0)
         grid.SetGridCursor(0,0)
         grid.EnableCellEditControl(True)
         grid.DisableCellEditControl()

wIA does not give much info on the parameters to  
Enable.CellEditControl...

Thanks
