Missing font warning -- but I don't appear to be using that font

I’m getting a missing font warning for Myriad Pro. (My PC was recently rebuilt and now I don’t have Myriad Pro.)

The problem is I cannot find ANY instance of Myriad Pro anywhere in my project. I have a bunch of movieclips in the IDE, and I have a dozen or so classes I’m instantiating. I’ve scoured all movie clips and all classes and cannot find Myriad Pro anywhere.

I guess it must be there somewhere but darned if I can find it. Any help finding it? Or any advice about what might be causing Flash to think I’m using it when I’m not?

Thank you!
