Hi Folks,
I looked through some of the threads and only seem to find the opposite problem of mine. What I'm experiencing is that my menu almost displays as expected in IE 7 but not in FireFox or Chrome. What is happening is that the background seems to appear for the drop-down without hovering over it. That said, I added a specific width to the ul.MenuBarHorizontal for centering purposes and if I set that to auto then I don't have the problem, but then the menu isn't centered and yes I'm using a div tag. The URL is www.computersales.mobi and any ideas are greatly appreciated.

Here's the code if you're interested:
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="33" nowrap="nowrap"><div id="navcontainer"> <ul id="MenuBar2" class="MenuBarHorizontal">
