OK, until I can get this setup locally, can someone test a page for me and maybe see what the problem is? This site http://tinyurl.com/2hk4h9 works for me in IE6, IE7, FF2, Safari Beta on my XP and 2K machines. My client says that on his IE6/XP the main content shows up below the left-side navigation. I even made for him this set of tests: http://tinyurl.com/28tt4d each of which has a different value for line 40 of the CSS file called 1.css, 2.css etc. This line changes the width of #wrap_left. He says none work. I could try to make more but I wonder if something else is the issue? Any ideas are appreciated. Thanks.
