Tony,

 I am having this same problem.  Below is my code in the aspx file as well as the styles from the master css file.  I am using .NET CLR 3.5 in Visual Studio 2008.  Thanks - Andrew

Master CSS File:
body
{
 font-family:verdana;
 font-size:small;
}

a:hover
{
 color:white;
 background-color:#223E6E
}

a:visited
{
}

a
{
 color:#223E6E;
}

td.FieldTitle
{
 font-weight:bold;
 font-family:verdana;
 font-size:x-small;
}

td.FieldValue
{
 font-family:verdana;
 font-size:x-small;
}
 
input.textBox
{
 height:20px;
 font-family:verdana;
 font-size:small;
 background-color:#E8E8E8;
 border:solid 1px #898989;
}

span
{
 font-family:verdana;
 font-size:small;
}
