no hack just a template edit right now:
postbit_bbcode_code:
HTML Code:
<span class="smallfont"><b>Code:</b></span><br />
<div style="border: solid 1px black; padding: 8px; background-color:white; color:black; width:600px; height:100px; overflow:auto;"><pre>$code</pre></div>
<br />

that's all.
i'll change it in future, to make it more dynamical acording to codelength... but for now it fits i think
