Thanks scurrell, I didn't notice that.
Inteligent Search results are now listed as they should be, I believe: I tried this in FF3, Chrome and IE8.
Here is new CSS code:
/*
Admin Area v3 - no header, less scrolling, CSS "hack"
http://forum.whmcs.com/showthread.php?t=33988&page=2
*/
body { background: #FFF url(images/headerbg.jpg) repeat-x -0px -110px; }
#content_container { background-color: white }
#topnav { padding-left: 20px; padding-right: 20px; margin:0; max-width:100%; background: #000; -webkit-border-bottom-right-radius: 8px; -webkit-border-bottom-left-radius: 8px; -moz-border-radius-bottomright: 8px; -moz-border-radius-bottomleft: 8px; border-bottom-right-radius: 8px; border-bottom-left-radius: 8px; }
#logo, #intellisearch strong, #intellisearch br { display: none }
#intellisearch #searchresults strong, #intellisearch #searchresults br { display: inline}
#intellisearch { background: none; height: 0px; margin: 0; padding:0 }
h1 { font-size: 14px; height:18px }
#bodyContentWrapper { min-height: 65px; }
#headerWrapper { height: 66px; }
Those lines should be added at the bottom of admin/templates/v4/style.css file.
