[thelist] Style sheet problem!

On a site I am redesigning, I'm trying to use style sheets to
primarily control text and color attributes.  On one page a table is
getting messed up due to style sheets when rendered by Netscape 4.7.  The
page is rendered just fine until I do something like add some <b> tags.

If you are running Netscape 4.7 or thereabouts please have a look to see
what I mean:

Here's the stylesheet:
<!--
BODY {
	background-color: white;
}

.mainbody {
	font-family: arial, helvetica, sans-serif;
	font-size: 12pt;
	color: black;
	background-color: #cccc99;
}

.minorbody {
	font-family: arial, helvetica, sans-serif;
	font-size: 12pt;
	color: black;
	background-color: #ffffcc;
}

.bottommenu {
	font-family: arial, helvetica, sans-serif;
	font-size: 10pt;
	color: black;
	background-color: white;
	text-align: center;
}

.rightmenutop {
	font-family: arial, helvetica, sans-serif;
	font-size: 10pt;
	color: white;
	background-color: #336699;
}

.rightmenu {
	font-family: arial, helvetica, sans-serif;
	font-size: 10pt;
	color: black;
	background-color: #cccccc;
}

.tracker {
	font-family: arial, helvetica, sans-serif;
	font-size: 10pt;
	color: blue;
	background-color: white;
}
-->


Any ideas?? Is it just a bug with netscape?  Any known workarounds?
