I am trying to add an external link to the text of my main page. Unfortunately, somewhere in Zen Cart it has decided to parse this link into an internal link, as though it is assuming I was too stupid to write a link properly.

It is taking http://[other site].net/
And turning it into:http://[my site].com/products/[actual link]

How do I make it stop doing that? I'm completely comfortable editing php files if that's what it takes to make it function correctly.
