No you are not the only one who experiences this. As noted, when using variable sized text for user friendly sites, the common font size is x-small. Now when using varialbe sizes you will find that ie displays a reasonable size, but when in ns it is always smaller. The ideal thing to do is make a javascript loader which checks for browser ie or ns and then points to a specific css.
<script language="javascript">
if (document.layers) {
document.write('<link rel="stylesheet" href="css/netscapechannel.css" type="text/css">'); }
else if (document.all) {
document.write('<link rel="stylesheet" href="css/iechannel.css" type="text/css">');
} else {
document.write('<link rel="stylesheet" href="css/netscapechannel.css" type="text/css">');
}
</script>
hope that helps
