[SOLVED] Pointing to menu2 causes an annoying bounce in the center column & sidebars

Here's my url: http://thebusinessplanitcom.ipage.com/jrda/

When you hover on any item in menu2, the whole rest of the page bounces down ever so slightly...making my site look crappy and amateurish. I can't figure out where to fix it. Pardon the complete undone-ness, I'm still very much in production and this little (hopefully simple) thing is slowing me down.

I'm using 3.5.3 on WP 3.0.1

TIA Everyone!!
