Bug?

I want to have some html on my site, so other people can use one of my banners, on their site. I used the simplecode from her https://www.tamba2.org.uk/files/simplecode.php?mode=process

I generated this code with it :

<a href="https://jimboscorner.dk" target="_blank"><img src="https://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>

And the output was this:


<code>
<a href="https://jimboscorner.dk" target="_blank"><img src="https://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>
</code>


Then i pasted the output to my WP 2.0 page, that i made specialy for banner.

But there seems to be an error, because when save the page the outcome has changed to this:

<a xhref="https://jimboscorner.dk" target="_blank"><img xsrc="https://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>

What makes the x marks before ‘href=’?
