[Wordpress issuses] auxclass on "Code in Forum Problem"

In this thread - http://en.forums.wordpress.com/topic/need-a-little-help-in-dns-editing?replies=6

no matter what I tried - I ended up with the extra formatting - was just a simple copy and paste using the Code buttons - copy from Notepad++ - - I thought this used to be straight forward

Any thoughts ?

The blog I need help with is captnmike.com.
