Did you check your site in Google Chrome? Layout looks strange to me...

Do not use tables for site layout. In your case I would use an unordered list for the menu.
Tables are for tabular data, not for layout. CSS is for layout.

What does this JS code do?

<SCRIPT LANGUAGE="JavaScript"> 
			<!-- Begin
				jsver = "1.0";
			// End -->
			</SCRIPT>
			<SCRIPT LANGUAGE="JavaScript1.1">
			<!-- Begin
				jsver = "1.1";
			// End -->
			</SCRIPT>
			<SCRIPT Language="JavaScript1.2">
			<!-- Begin
				jsver = "1.2";
			// End -->
			</SCRIPT>
			<SCRIPT Language="JavaScript1.3">
			<!-- Begin
				jsver = "1.3";
			// End -->
			</SCRIPT>

Code (markup):

To be honest... this site's HTML markup is pain in my eyes, very bad code...
