Help on tut "Flash-Based Email Form Using PHP"

I followed and used this tut, but it seems there is one problem.

I had to put the entire “form” and the buttons in a movieclip itself, that lets the form and the other text “fade in”.

The problem itself happens when the fading in occurs : The movieclip that holds the form starts blinking between the form and the thank you page for as long as the parent movieclip is playing the fade in. When the fade in stops (stop on parent movieclip) the blinking stops.

I don’t know how this is possible as the first action in the form movieclip is ‘stop()’

any help plz…
