Text field position, and font color and face problem in Flash MX

My problems are
1, I can use mouse to drag the screen and mulscreen position when I am in the leftside, then I press the front, I can still input there and drag it to someother place. But when I goes back to the leftside, the textfield’s position changed to the same as the the ones on the frontside. How can I save the position on each side as its variable, so that when I come back to the side, the position on that side can show in right way. Do not let them move together.

2, the problem still happen after I click to turn to the front, the font color of the one on the leftside disappear when I come back. And strange thing is that it is only wrong for the screen mc, but not for the mulscreen mc.

3, It is about the font face combo box, I can see its effect on both of the input textfield, but they are not working on the dynamic textfield inside the screen and mulscreen movieclip.

here is the link of my work.
