I am making a movie that has classes.  
There is one MovieClip in the movie and it needs to have a blank base class, because one of the classes is a Dynamic.

Flash 4 keeps auto-filling in the base class: flash.display.MovieClip .  
How do I stop this from happening?

There is no preference to change the setting.

Thank you
