Try writing <br> - I guess the form-input isn't changed, which means this shows up as literal text in HTML - in which that particular string has meaning and is interpreted by most browsers.

Hugo.

Grmbl.
I counted on these tags also being expanded - they weren't.

Try <br>

Hugo.

Here is where the problem occurs:
http://www.php.net/source.php?url=/include/layout.inc

/* this 'fixing' code will go away eventually. */
$fixes = array('<br>','<p>','</p>');
reset($fixes);
while (list(,$f)=each($fixes)) {
    $text=str_replace(htmlspecialchars($f), $f, $text);
    $text=str_replace(htmlspecialchars(strtoupper($f)), $f, $text);
}

Thats a good reason to use <br />. We can't fix that anyway.

Thank you.
