I got a slight problem with honizontal nav bars in Netscape6.2.

If I float the elements <ul><li><a> left, it fails in Netscape6.2. Also, i recognized, that on alot of css-guru-sites the horizontal-nav-bar is made by the 3-float rule, as i've mentioned above, and... yes .. fails. The solution might be: display: inline. But what is the reason to let the navigation fail in N6??? Most of N6 users upgraded to Netscape7???? Please let me see the sun again... How do you handle your horizontal nav bars?
