Disabled combo boxes don't display properly after loading a movie.

Question

Hi,
I have a main movie that contains some combo boxes. Some of them may be disabled.
By pressing a button I load another movie using loadMovie. The loaded movie also contains combo boxes.
When the button is pressed, the clip that shows the combo boxes is removed from the stage and the loaded movie is displayed. By pressing another button, the loaded movie is unloaded and the clip with the combo boxes is displayed again.
Well, once the other movie has been loaded, when I go back to the clip with combo boxes, the disabled combo boxes have a small gray button covering the black down arrow.
I have determined that so long as the loaded movie contains combo box in the library, the problem occurrs, even if there is no actual instance of it.
The combo boxes that are not disabled are not affected. The combo boxes are disabled by setting "cb_name.enabled=false".
If the combo box is enabled, it displays correctly, but if disabled again, it goes wrong again.
My project is targeting Flash 8, so it uses AS2.
I'm using Flash CS4.
This is a very simple example I did to make sure I wasn't doing anything funny:
Initially:
After pressing the button:
After pressing the other button:
The behaviour in a web browser is the same...
I hope someone can help me with this. Thanks in advance!

Thanks for the response.
The "Load the movie" button:
on(click)
    _parent.gotoAndStop(2);
The 2nd frame:
loadMovie("Test another child.swf",Container);
stop();
The "Unload and go back" button:
on(click)
    unloadMovie(_parent.Container);
    _parent.gotoAndStop(1);
Container is a movieClip with a dark gray square shape the size of the movie clip that is loaded. It doesn't exist on frame 1, only on frame 2.
The combo boxes are inside a movie clip, and this is only on the stage on frame 1.
This and the captures belong to a very simple test I did. If there is a way of posting files, I can post a zip file with the two .fla and the two .swf.
