LogoWrapper is overlaping NavMain (Only in dreaded IE)

[flipjargendy]

I created some icons to use instead of plain text on my navMain. All looks and works well in Firefox. I've started making changes for all of the bugs in IE though. This one I cannot quite figure out on my own.

I've attached a screen shot. I've shortened the width of LogoWrapper so that you can see what is under it. Here is the CSS for both of those objects:

#logoWrapper{
    border: 0px;
    background-color: #FFFE9A;
    height: 77px;
    width: 755px;
    }

#navMainWrapper {
    margin: 0em;
    background-color: #FFFE9A;
    padding: 0px;
    font-weight: bold;
    color: #000;
    height: 8px;
    border: 0px;
    }

#navMain ul, #navSupp ul, #navCatTabs ul {
    margin: 0;
    padding: 0em 0em;
    list-style-type: none;
    text-align: center;
    line-height: 1.5em;
    }
