#myMenu li:hover

#myMenu li a:hover
{
    background-position:left bottom;color:#093D64;

}

this is the style of ddr:menu .

it works very fine in all main 5 browsers, but not in IE6, which become hidden.

Is there any mistakes in the above css id, or maybe some changes have to be made in order to work in internet explorer 6.

Please advice
