"blinking" when changing states
We seem to have encountered the same problem from here. We also have our own character that we created and we used states to change the movement of the character.
We made use of flash movies so as to make the character, for example, fly and then walk.
But as we published our story, everytime there is a state change the character disappears for a split second. Before going to the next state/movement.
We tried the solution of Tara but it doesn't work on our end. We also checked the flash movie but it doesn't have an extra white frame in the flash movie.
I've read around and it seems to be random. but for us it is happening most of the time even when the story is published or previewed.
