I see a different layout in Opera and IE/Firefox. In Opera 7 the closing border is double high as in IE/Firefox. With a little help from Krow we use this in the stylesheet:
/* Rule for all Browsers */
.tdheaderb {
background: #224988;
height: 10px;
}
/* Windows IE ignores the following */
html>body .tdheaderb {
height: 5px;
}
this works for me and display in all browser the same border.
