Ok I found the problem

I edited includes/languages/ENGLISH/header.php as instructed by the tutorial above. Nothing happened. So I changed the image file name to logo.gif and it worked. But when I changed the define('HEADER_ALT_TEXT', definition, nothing happened. So I searched for more header.php files and found one in includes\languages\english\pure_green_free So I edited that and it worked! So for some reason, either the tutorial is wrong or something screwy is going on with my install?

Also I have an issue with IE. The new logo works fine in FF:



But in IE it gets hidden by the navbar?



Any ideas?
