That is because it is only triggering the event once and more than one fied
is modified. There is a property of the TIB_Row being passed in that has a
TList of the modified columns when there is more than one.

Can't remember exactly how it is spelled but I think it could be
ModifiedColumns or ChangedColumns. You will need to cast them as a
TIB_Column when looping through the list.
