IE5.0 verse ie 6.0

[md_huhn]

I have an HTML page that forces line breaks between Lined items "<LI>" in an outline. The problem is that these forced line breaks appear when viewing the page in IE 5.0, but not in IE 6.0? What is the difference and how can I get them to appear in both browsers?

Here is a sample of my html page.

Thanks,
M
