Im no expert, but I would try this (dunno if it’ll work though):
have the text fields in a seperate MC that loads the text file there… then have the entire MC fade in with the text already loaded. Hope that is clear… let me know if it works!
Well it may not be possible - one thing you could try is to make a MC that is a block the same color as the background and the same size of your text field. Place it over the text and have it fade from 100% alpha to 0% - kind of crude, but you could give it a whirl.
Peace
