I have been using Flash for a few years in an educational environment. When instructing students to make motion tweens I always tell them to convert the object to a symbol and choose a graphic symbol. I only have them use Movieclip symbols when they need nested animations or need to reference the symbol with actionscript.
My question is, why use the graphic symbol at all? why not make every symbol except buttons movieclip symbols?
Is there something about the graphic ymbol that keeps the file size low or someother limitation with the number of possible movieclip symbols?
Besides differentiating symbols in the library from still symbols to nested animations what is the purpose of the graphic symbol?
