2 combox problems (tween and drop down sizing)

Can anyone help me solve one or both of these issues? When you click on Reservations in the following link, you will notice that the default values of the combobox populate immediately despite being contained in a SWF that is tweening in slowly via Tweener. Any idea what it is about these values that they aren’t getting message to fade in along with their counterparts?

Secondly, you’ll notice if you resize the browser, the entire page resizes accordingly but the drop down of each individual combox does not. Its always the smae and looks very funny when the screen is very big or very small…any idea how to control that too?
