Firefox problem with embedded swf

Hey, hopefully this is easy for you smart peoples to solve. <- that’s my site
I just added my first embedded swf - it used to be just an image…now the footer has links.

In firefox i’m seeing a tiny bit of repeating graphics at the bottom…it’s from the simpleviewer repeating background image, it doesn’t show in ie for some reason…can anyone help make it dissapear in firefox?

I was thinking maybe by making a slightly smaller border or something it might go off the edge of the screen?

thanks in advance for any help.
