Browser - problem with multiple SWFs on one html page

Hi, I’m new the Kirupa forums. Hopefully somebody here can help me out.

I have several SWFs placed in the same HTML page. Two of them currently have rollover states but the top one (the email address) doesn’t always work. Usually its
when after when I’ve scrolled down to the bottom of the page and moused over the SWF at the bottom (the ‘go to top’ button). I’m assuming the top one is losing focus somehow. Anybody have any ideas how to fix this? Here’s the link:

Any help is appreciated. Thanks!
