Hiding a Graphic in only a MC and nowhere else

View the link, click the HOME button. .LINK

Notice the brown elasticy thing, you can see it on top of the main toolbar and the word home, i need to mask it somehow so that it appears to be underneath the toolbar. I can’t just stick a pice of the toolbar graphic in the MC because the button in the layer underneath dissapears.

In Summary:
I need to hide the elasticy button but nothing else, i need to hide it in the MC it’s in and ONLY that MC.

Help plz

Dont tell me to search “This has already been ansered” I did
