Well here is what my header looks like on Firefox and Google Chrome:
...and here is what it looks like on IE:
As you can see there is white space in between the the large logo and menu, and another white space between the menu and the rest of the site. Here is my code for my header:
Code
<div id="socialnetworks">
<a href="http://www.facebook.com/group.php?gid=111304995551"><img src="/design/socialnet/facebook.png" border="0"></a>

<a href="http://youtube.com/SocomTube"><img src="/design/socialnet/youtube.png" border="0"></a>
<a href=""><img src="/design/socialnet/rss.png" border="0"></a>
</div>
<div id="header">
<div id="header_block">
<div style="background: url('/design/header/header-bg.png') repeat-x;">
<img src="/design/header/header.png">
</div>
</div>
</div>
<div id="divider">
<center>
<table cellspacing="0" cellpadding="0" border="0" style="height:33px;widht:100%;">
<td style="background: url('/design/header/menu/lpane.png') repeat-x;width:379px;height:33px;">
</td>
<td style="width:59px;height:33px;">
<a href="/index/main/0-4" onmouseover="document.home.src='/design/header/menu/homeh.png'" onmouseout="document.home.src='/design/header/menu/home.png'"><img src="/design/header/menu/home.png" name="home" border="0"></a>
</td>
<td style="width:90px;height:33px;">
<?if($USER_LOGGED_IN$)?>
<a href="$PERSONAL_PAGE_LINK$" onmouseover="document.myprofile.src='/design/header/menu/myprofileh.png'" onmouseout="document.myprofile.src='/design/header/menu/myprofile.png'"><img src="/design/header/menu/myprofile.png" name="myprofile" border="0"></a>

<?endif?>
</td>
<td style="width:95px;height:33px;">
<?if($USER_LOGGED_IN$)?>
<a href="$USERS_LIST_URL$" onmouseover="document.memberlist.src='/design/header/menu/memberlisth.png'" onmouseout="document.memberlist.src='/design/header/menu/memberlist.png'"><img src="/design/header/menu/memberlist.png" name="memberlist" border="0"></a>

<?endif?>
</td>
<td style="background: url('/design/header/menu/rpane.png') repeat-x;width:377px;height:33px;">
<div id="search"><?if($PAGE_ID$='userslist')?><?else?>$SEARCH_FORM$<?endif?></div>
</td>
</table>
