Finished tutorial does not work in IE6

Hi,

The completed html file that comes with the CSS Photoshop tutorial and which is located at PATH\CCS4PS\Completed Files\CSS Designer Layout.htm does not work correctly in IE6.

Specifically the content div starts below and to the right of the sidebar div instead of starting at the same vertical position as the sidebar div. This happens if the files are local or uploaded to a server.

Also something else curious happens only when uploaded to a linux server. All versions of IE but not Firefox stop displaying the colored nav squares. In addition, the footer text bleeds out of the wrapper to the left. Below are unaltered originals from your download. The index file is there in case the spaces in the original file cause a problem but it's a copy of the oringinal and these files were never opened in Dreamweaver.
CSS%20Designer%20Layout.htm
index.html

Could somebody explain what causes these errors?

thanks
