Multi Level Flash Horizontla menu

I am trying to create a mulitlevel horizontal flash drop down menu. It’s coming along but I have a few issues.

  1. I would like to make the text in my Main Menu a different size say (16) and the one in in my sub menu say (12).At present I had to make it 9 for all buttons so that i could fit all my text with some sub menus.
  2. When I rollout the menu it doesn’t dissapper until i either rollover another menu item or click on an empty space.
    3)I would like it to fit the stage width and not overlap
    I have attached my fla code and xml file. Please assist
