IIRC there is a debugger for this, but my guess is that when the new cell 
is entered, it receives one of the cell selection events, while the old 
cell also gets a key down event. Possible solution: check if the editing 
was already disabled before making the EnableEditing call. Possible design 
enhancement: make an editing_enabled property for the grid instead (such 
that the setter only makes the state-change - implicitly triggering the 
event - when the set state is not the existing state).
