Can CodeIgniter change .htaccess all by itself?

By app code do you mean addons that I downloaded? I haven't added anything to CI. I just have my "scripts" (if you even call them that). I've made controllers, models, a couple helpers, and extended the form validator. I haven't written any code that alters .htaccess.

I guess tell my host that, no, I don't have any .htaccess changing code.
