Modified the code so now when you hover over a link it will hilight the words, not the background. Works with google search, images, maps and video & same with alltheweb search, images etc. Feel free to add any ol site you wish or to change the colour of the hovered text.
Original work done by USBman@userstyles

Edit 25.04.2008: Cleaned up the code little bit and added http://userstyles to url's.
