Hi rfl. Yes, ideally post a link to the site so we can check it out. CSS alone is of no use, as we need to see the HTML too.
It's crucial to test your pases as you build them, rather than after the fact, so that you can catch problems as they arise. IE8 is a fairly reliable browser, so from that screen shot, it looks like there is a major flaw in the way the page is coded. Anyhow, post a link and we'll have a look.
