Help a poor newbie, kind designers:)

hi. like i said in the title, i’m (still) a newbie in flash, so i have a n00b’s problem… i’ve seen in many many flash sites that they can load different parts of the flash asynchronously (not at the same time). how is that done? does the flash have included more than one movie (not movie clip) inside it? how do i, for example, show the user a picture is loading, or my menu?

yes, i know you’ve seen this a zillion times before and you’re prolly booored:asleep: can you please try to help me? i wanna get into this flash thing really seriously:)

thank you
