IE bug with Gridview Row borders?

[Acladeus]

I've seem to have encountered a bug with IE6 and the displaying of row borders:

I have the following style defined,

.tableRowSelected
{
background-color: #33ffff;
color: #000000;
font-size: 10pt;
font-family: Arial;
font-weight: normal;
border-right: black 2px solid;
border-top: black 2px solid;
border-left: black 2px solid;
border-bottom: black 2px solid;
}

The idea is that when the row is selected, the row will be highlighted with a black border around it.

This works fine in Firefox but in IE only the background colour is displayed, with no borders!

Any ideas please?

Best wishes,

Johan
