When you attach a movieclip taken from the symbol library to the Stage, by using the attachMovie function and its Linkage name, do you have to - previously - place a dummy instance of the mc anywhere on that Stage to get it works ?
If you didn’t check the Export in first frame option in the Linkage Properties of the symbol, the answer is yes. 
DOH ! X-)
for a while, was wondering what could this option be used for ?..
Why does Macromedia doc so poor sometimes, especially on tricky topics ?.. :-/
Ok, I don’t need to place this useless instance on the stage anymore now. Thanx Kode 
No problem.
And actually, I’d recommend you to keep dragging an instance onto the stage; you could have some preloader issues exporting it in the first frame.
mmmh… I see. Ok.
Ok!
