I posted a bug yesterday regarding the current plugin system.  If in 
config.php I change the default css style sheet into the following 
pattern:  ../themes/css/sans-10.css  or just sans-10.css I receive an 
error on any of the plugins page (a 404 error) and the style sheet is 
not included.  The reason is because it needs to look for it one 
directory behind the one it starts in.  The issue is on page_header.php 
in the "functions" directory starting on line 31.  The current code reads:

if ( !isset( $custom_css ) || $custom_css == 'none' ) {
    echo "<link rel=\"stylesheet\" type=\"text/css\" href=\"$theme_css\" 
/>";
}

I'd like to suggest that the following code be used instead:

    if ( !isset( $custom_css ) || $custom_css == 'none' ) {
        $file = pathinfo($theme_css);

        if ($theme_css != '') {
            $a = dirname($theme_css);

            if (!realpath($a)) {
                $path = "../" . $a;
            } else {
                $path = $a;
            }

            $css = $path . "/" . $file['basename'];

            echo "<link rel=\"stylesheet\" type=\"text/css\" 
href=\"$css\" />";
        }

Reason, this first grabs the directory from where the css file is 
located, and then check to see if the file exists (realpath()) and 
chooses how many dirs to go back.  Right now this seems to work, there 
may be other instances and I'd be more then happy to mod this code, but 
for now this covers the issues I was facing.

Let me know what you all think.  Thanks.
