It looks like this on my laptop, with Windows Vista and IE7. The menu is placed on top of/over the header. In IE6 (on Windows XP) it does however look like this:

The menu is now placed underneath the header. Is there a way to fix this?
This is part of the stylesheet code which is probably causing the problem:

we will hide text and replace it with a image
we need to assign a height for it so that the image wont cut off
*/
div#header {
height: 100px; /* adjust according your image size */
}
div#header h1 {
/* you can set your own image here */
background: #A9261F url(uploads/images/achtergrond5.jpg) no-repeat 0 0px;
display: block;
height: 122px; /* adjust according your image size */
width: 750px;
text-indent: -999em; /* this hides the text */
text-decoration:none; /* old firefox would have shown underline for the link, this explicitly hides it */
}
div#content {
margin: 1,5em 0em 0em 0em; /* some air above and under menu and content */
}
