Hi,
the captcha is a part from the forms.
You can't put it in a iframe.
Test this option:
open global.php
and edit this code to make it smaller:
$captcha_length = 5;
$captcha_width = 200;
$captcha_height = 70;
$captcha_text_size = 25;

One post for this problem is enough. Second post deleted
here is the problem: i put a captcha in shoutbox:
