Hi, I think this is a Javascript issue, but I'm not sure, maybe you can help!

It's pretty simple - all the boxes on kellyforcouncil.com turn gray when the mouse rolls over them, and I don't know why! They just started doing this when I added an email signup form on this page: http://kellyforcouncil.com/?page_id=59

I've looked through the page source but can't figure it out. Any help you can offer would be very appreciated. Thanks!

You have a script that is adding a class called "over" to the <tr> that holds the page content.
The script contains this:

jQuery(".post table tr").mouseover(function() {jQuery(this).addClass("over");}).mouseout(function() {jQuery(this).removeClass("over");});

If you don't want anything to change to a gray background on mouseover, you should be able to just get rid of those lines. If you want certain parts to turn gray on mouseover, then add a more specific selector for those areas. Maybe give them a special class.
