File size - best approach

hi,

i have a flash file with buttons on it. the buttons need to load content into a higher level. the content uses scrollers and also a button to remove the movie.

which is the most efficient approach

  • the buttons load swf files so these only load when called?
  • have the content in movie clips and call these from the buttons?

i assume the first approach is best but would like to know if it is possible to use movie clips without them all loading at the start.

cheers
mark
