Masked hitTest();

Hi there, i have a movie in a full swf mode, and ain it i have a menu that has a hitTest() command for showing and hiding, i’ve masked the menu and when i published i noted that the hitTeste it’s still affecting the movie out of the mask.

The mask has the same size of the stage (800x505), i’m wondering there’s any way to mask a hitTest() in theis movie?
