Well I do not thing that it is unexplainable how this work. The rule of 
thumb is simple. IF the record your are looking is bellow the current 
view then it will be the last raw on the view after selected, if it 
above it will be the first. It is possible to be in the middle if it is 
already in view. You can have a consistent effect if you move to the 
first record before using locate, I do not know if this is what you are 
after though.
