I'll take a look at your game throughly after work,

if i'm not mistaken, i've read about this problem last time on forum, check on your movie clip that has the sound inside your library, look into it's linkage, try uncheck on 'export on first frame' so it'll load the sound later and make the loading bar appear first. that even applies for big file sized picture that you put on the first frame of your flash movie, which sometimes makes you woner why your loading bar only appears even ater 70% loaded, its' because probably if your movie is 500kb, the loading bar's picture/effect already took up 400kb.

saw it at a glance, good work. will check it later
