Netscape 4.x has a strange rendering bug with checkbox and
radio button form fields. If a BGCOLOR attribute is declared for a table - or a
cell within a table - the rendering boxes of any checkboxes and radio buttons
(also INPUT FILE fields to a small extent) in that cell/table will not use the
indicated BGCOLOR - it will instead use the BGCOLOR of the document itself.
If you use Netscape 4.x, you will see this bug apparent at almost every large-scale site you go to.
BODY uses BGCOLOR=red to create extreme contrast to exhibit the behavior
