This is not a bug :-)

It is possible because the Data event is raised when the TableView is redrawn.

As you display message boxes, the TableView is redrawn whan a message box is 
hidden, just before the other is shown, and so some Data events are raised, 
and so the Result object is moved after each Message() call.

Use the PRINT instruction instead of Message boxes, and the problem 
disappears.
