Help: Tooltip in a MC (.fla attached)

[ContactoCreatvo]

The tooltip works when is in the _root... but it doesnt when i insert it in a MC... i have some problems with actionscript... so if any can help me...

What I generally do for tooltips is.. create the tooltip as a MC.. then I hide the MC using mc._visible=false; then activate it however I need using mc._visible=true;
