Shifting text in MLEADERS

If i add a leader with text that is left justified and then edit that
text so that the distance between then end of the leader and the middle
of the top line changes it actually moves the text instead of adjusting
the length of the leader landing.

You'll notice in the attached picture that the note changes position in relation to the green vertical line.
You can also try it inthe attached drawing.
PLEASE....Any ideas on why this would be happening, it's extremely annoying.



Thank you in advanced,
