It seems the background-color property is not working properly  if I put this into my CSS

 

.AjaxUploaderAttachmentsTableRow
{
        color: green;
        background-color: yellow;
}

 

The 'green' attribute works, but the yellow does not (???)

 

If I do this....

 

.AjaxUploaderAttachmentsTableRow TD
{
        color: green;
        background-color: yellow;
}

Then the background-color setting works....why do I have to add the TD subelement?  Why isn't the style cascading down from the TR like the 'green' attribute does?
