what is your "splash screen" (bitmap, movieclip, something else) and where is it (in your flash library, on-stage, outside flash, somewhere else)?
my splash screen is a movie clip ... its in a different scene then the rest of the game
it's not a good idea to use scenes with as2. use frame labels and the goto methods, not functions.
insert a new keyframe at frame 1 and manually move your splash movieclip there. attach a stop() to that first frame.
