spacing issues in IE7 -- help!

[archaeologist]

:confused:
Everything looks great, except there is a small space divs.
There is a picture of what's happening here:

You can see the breaks in the left and right corner and bottom left.
I don't know how to fix this or what's causing it. At first I thought there might be div paddings that were causing it but i checked those and it seems fine. I am creating the site with ASP.net.

CSS:
* {
margin: 0;
padding: 0;
}

/* retag */
body {


}
p {
margin: 0;
padding: 0 0 0px 0;
font: 11px/17px "Lucida Grande", Tahoma, Verdana, Arial, sans-serif;
color: black;
}

h3 {
font: 16px/22px Helvetica, Arial, sans-serif;
color: black;
padding-bottom: 15px;
}
td, div, span {
font: 11px/17px "Lucida Grande", Tahoma, Verdana, Arial, sans-serif;
}
ul, ol {
margin: 0;
padding: 0;
}
li {
font: 11px/17px "Lucida Grande", Tahoma, Verdana, Arial, sans-serif;
padding-bottom: 10px;
color: black;
}
a {
font-weight: bold;
}
a:link {
color: #ED667A;
}
a:visited {
color: #F697A5;
}
a:active {
color: #FFF;
}
a:hover {
color: #E8DAC1;

}

html * {

which div or class is wrapping those images?

[archaeologist]

mastheadimg - wrapping the top image (not visible in photo)
wrap - wrapping the entire body of images
threecol - wrap the three columns of information/pictures

does this help?

[Apostropartheid]

Why would you define Lucida Grande and not Lucida Sans Unicode? They're essentially the same fonts (MS and Apple have a deal for a few web essential ones to be cross-platform compatible.)

maybe ...

html, body {
padding: 0;
margin: 0;
border: 0;
}
