Flash comboBox Component Bug

Bugs in Flash comboBox component.
I used this fix detailed on http://lailablog.blogspot.com/2005/12/flashs-combobox-component.html
Worked nicely.

"The ComboBox component in Flash does not behave as expected if used in a movieclip loaded by loadMovie or attachMovie. What happens is that the ComboBox won't open, as if it doesn't react to events.

1. Drag an instance of the component onto the stage of the movieclip that's loading the movieclip containing the ComboBox. It can then be deleted, the point is that the loading movieclip has the component in its library. This appeared to solve the problem for a lot of people.

Also theres a lockroot solution which I didnt try but is documented here:
