minor side note unrelated to your actual issue -- you have what appears to be a heading, why are you using a bold tag?
Also, beware that :hover on anything other than an anchor doesn't work on really old versions of IE -- if you care. You can use this to fix that:
But really with IE7/earlier heading out the door, it might not be worth the effort for a minor visual effect.
Though if that hover is actually going to do something like be a link that goes somewhere, put an anchor inside that DIV and keep the BOLD tag... though that would mean you can't get a proper heading in there or paragraphs around the text.
