VBA - Change fonts of all objects?

(PPT 2003 mostly and sometimes 2007)

I made a macro for replacing ALL the Arial fonts in my presentation to
the font Broadway using:

ActivePresentation.Fonts.Replace Original:="Arial",
Replacement:="Broadway"

But I noticed it doesn't change fonts in certain objects like charts
and wordart. Are there others it doesn't change? What code do I need
to do change every text object using Arial to Broadway?

Thanks,
Melina
