I have add style for TR:
<TR  ID='AddAttachmentSection' style='display:none;'>
and use javascript to control is display:
var attachmentSectionShown=false;
var attachmentsShown=true;
function toggleAddAttachmentSection()

under the TR

Change from:
     <TR  ID='AddAttachmentSection' style='display:none;'><TD>
				<TABLE>
				<TR><TD>HELLO, MOZILLA</TD></TR>

Verified, I guess, but this is a slightly different issue... Just using ""
instead of "block" will fix the page in question ("block" on a table row does
something quite different from the default "table-row" display value in all
browsers but IE).
