To fix the IE6 issue, add the CSS below to the IESpecific.css file inside of the skin directory (/Data/Sites/1/skins/i7media-2horizontalmenus/).
.center-nomargins, .center-rightandleftmargins, .center-rightmargin, .center-leftmargin, .rightside, .leftside{
padding-bottom: 0px !important;
margin-bottom: 0px !important;
}
img.bg{
display:none;
}
You will have to open and save your web.config for the change to take effect because the skin is cached on the server.
I am still working on the IE7 issue.
HTH,
