Hei.  
I’m going through my library and trying to reduce size from my App by changing the unanimated elements from MovieClips to Graphics

(From Cs4 help:“Use graphic symbols for static images … **Graphic symbols add less to the FLA file size than buttons or movie clips** because they have no timeline.”)

BUT, when i change a movie clip in the library to be a Graphic symbol, it doesn’t change the symbol’s instance on the stage.!

What does it mean when it comes to consuming memory??? Is the symbol’s instance on the stage is still a movieclip or a Graphic
