Sorry, but what do you mean exactly? When the menu slides out you can see through it to the stuff underneath that was loaded previously. In other words, roll over little piece of menu, whole menu slides out, click a button which loads content. Roll off menu and it slides back. Roll over menu again and when it slides out you can see through it to the stuff underneat that was loaded with the first button click. What would I mask exactly? Sorry for stupid questions . . .
