Margin at IE6

I added the margin at the top of the page but does not appear in Internet explorer 6, and that after the addition of shadow using pie.htc file
Before adding the shadow appears on the internet explorer 6

#logbar
{
behavior:url(PIE.htc);
margin-top:20px;
}

any help?

Do you have a link to the page in question as it will be easier to debug?

there are known issues mentioned in the documentation.
