Hello everyone!

I'm having a problem with my top nav bar on my site. It looks great in all the IE browers but when you view it in Netscape 4.7 one cell scrunches together. I've tried readjusting the cell width...but Netscape just ignores it...Help!

Here's my code:
<head>
<style type="text/css">
<!--
Body { font-family: Arial,Verdana, Helvetica, san-serif;color: #000099;}
.menulines a{text-decoration:none; color: #ffffff; font-family: Arial, Verdana, Helvetica, san-serif; font-size: 10pt;}
.menulines a:hover{color:#000099; font-weight:bold; background-color:#f2f2f2; }
.mainnav {font-size: 16pt;}
-->
</style>
</head>

<!--Horizontal navigation bar starts here-->
<div align=right>
<TABLE BORDER=0 CELLSPACING=0 WIDTH="750px">
<TR>
<td width=50%>&nbsp;</td>
<td class="menulines"><center><b><a href="http://www.cmtonline.com">Home</a></b></center></font></td>
<td class="menulines"><center><b><a href="http://www.cmtonline.com/backgroun.html">Company</a></b></center></font></td>
<td class="menulines"><center><b><a href="http://www.cmtonline.com/staff.html">Contact Us</a></b></center></font></td>
<td class="menulines"><center><b><a href="http://www.cmtonline.com/cims3.html">Software</a></b></center></font></td>
<td class="menulines"><center><b><a href="http://www.cmtonline.com/technical.html">Support</a></b></center></font></td>
</tr>
</table>
</div>
<!--end-->

If anyone has any ideas please let me know...I've been working on this problem for too long.

Thanks in advance!
