I've created a flash movie using a 4-layer photoshop file
imported to stage and added stops for 0% and 100% alpha color with
tween motions. It looks great except the transition from the last
layer back to the first. I've tried changing the beginning layer
from starting at 0% to starting at 25% and changing the final tween
to only fade to 25% instead of 0%. It's a lot better but still not
as seamless as the other tweens. Any suggestions or tricks?
