Aligning a MC or symbol

I have no problem in Flash 5.0 but MX wont let me align my center point of the MC or symbol to the top left (0,0) of the stage.

First the symbol. It’s center point is at center.
Then the symbol is placed inside a movie.
That movie’s center point is also at center.

Now when i want to align that MC’s center to top left by saying MC property and setting it 0,0 it align the top left corner of my MC to the top left corner of the stage.

What i want was the center point of the MC to be place at the top left (0,0) of the stage…etc…

When assigning the center point, and then telling MC to align at a certain place, isnt it supose to use the center point?..

somehow its not working…
